Question 2

Both C₂H₄ and C₄H₈ belong to the alkyne series.

Accepted Answer

The given codes represent chemical shift values in NMR spectroscopy and do not directly indicate belonging to the alkyne series.

Question 3

Hydrocarbon compounds are essentially nonpolar.

Accepted Answer

Hydrocarbon compounds consist of only carbon and hydrogen atoms, and their bonds are predominantly covalent, resulting in a relatively uniform distribution of electrons. As a result, these compounds have no significant polarity and are therefore considered nonpolar.

Question 4

The molecules of alkanes have strong intermolecular attractive forces and high melting points.

Accepted Answer

Alkanes have weak intermolecular forces due to the relatively small size of their molecules and their nonpolar nature. Therefore, they have relatively low melting points compared to molecules with stronger intermolecular forces.

Question 5

Name and write the formulas for the three structural isomers of pentane.

Accepted Answer

The answer of Name and write the formulas for the...

Question 6

Hydrocarbons are compounds composed entirely of carbon and hydrogen.

Accepted Answer

Hydrocarbons are compounds made up of only carbon and hydrogen atoms. They can range from simple hydrocarbons such as methane (CH4) to complex molecules like those found in crude oil.

A.Hydroxyl group
B.Carboxyl group
C.Carbonyl group located on the final (terminal)carbon atom of a chain.
D.Carbonyl group located on an interior carbon atom of a chain

Accepted Answer

The answer of Name the class of organic compound which...

Question 9

Carbon tetrachloride is a hydrocarbon.

Accepted Answer

Carbon tetrachloride is not a hydrocarbon. It is an inorganic compound composed of carbon and chlorine, with the chemical formula CCl4.

Question 10

Prepare a chart in which you name the four major homologous series of hydrocarbons,state the type of bonding found in each,write the general formula for each,write the molecular formula and name of the first member of each series.

Accepted Answer

The answer of Prepare a chart in which you name...

Question 11

2-methylpentane and 2,3-dimethylbutane are isomers.

Accepted Answer

Isomers are molecules with the same molecular formula but different chemical structures. In this case, 2-methylpentane and 2,3-dimethylbutane have the same formula (C6H14) but different structures, making them isomers.

Question 12

Write the balanced molecular formulas for the complete combustion of the first threemembers of the alkane series.

Accepted Answer

The answer of Write the balanced molecular formulas for the...

Question 13

Identify each alcohol as either primary,secondary,or tertiary.
A.1-butanol
B.2-butanol
C.2-methyl-1-propanol
D.2-methyl-2-propanol

Accepted Answer

The answer of Identify each alcohol as either primary,secondary,or tertiary.
A.1-butanol
B.2-butanol
C.2-methyl-1-propanol
D.2-methyl-2-propanol...

Question 14

Isomers are compounds that have the same molecular formulas but different structural formulas.

Accepted Answer

Isomers have the same molecular formulas but different structural formulas, which means they have the same number of atoms of each element but the atoms are arranged differently in the molecule.

Question 15

All the isomers of C₃H₈O have the same properties.

Accepted Answer

Isomers are different molecules with the same chemical formula but different arrangements of atoms, and therefore they can have different properties such as melting and boiling points or reactivity. Therefore, the statement that all isomers of C₃H₈O have the same properties is false.

Question 16

Urea was the first organic compound synthesized from inorganic compounds.

Accepted Answer

Urea was first synthesized from inorganic compounds (ammonium cyanate) in 1828 by Friedrich Wöhler, marking a significant event in the history of chemistry.

Question 17

Write the balanced molecular formulas for the incomplete combustion of the first three members of the alkane series.The products are carbon monoxide and water.

Accepted Answer

The answer of Write the balanced molecular formulas for the...

Question 18

Name the following compounds. A.CH₃CHClCHClCH₂CH₃ B.CH₃CCl₂CH₂CH₂CH₃ C.CH₂ClCH₂CH₂CHClCH₃ D.CH₃CHClCH₂CH₂CH₂Cl

Accepted Answer

The answer of Name the following compounds. A.CH₃CHClCHClCH₂CH₃ B.CH₃CCl₂CH₂CH₂CH₃ C.CH₂ClCH₂CH₂CHClCH₃ D.CH₃CHClCH₂CH₂CH₂Cl...

Question 19

Compounds with the general formula,RCHO,are carboxylic acids

Accepted Answer

Compounds with the general formula RCHO are actually aldehydes, not carboxylic acids. Carboxylic acids have the general formula RCOOH.
