Question 1

A unknown hydrocarbon undergoes the following general reaction.  Which type of compound might X be?

Accepted Answer

The general reaction given suggests that X is a compound with a double bond, which is characteristic of an alkene. The other choices (alkane, cycloalkane, and aromatic hydrocarbon) do not contain a double bond and would not undergo this type of reaction. Therefore, C) alkene is the best choice.

Question 2

Complete the following equation: C₃H₆ + Br₂ $\rightarrow$

Accepted Answer

The reaction between C3H6 (propene) and Br2 is an addition reaction where the bromine adds across the double bond, forming C3H6Br2 (1,2-dibromopropane).

Question 3

What is the name of the compound whose carbon skeleton is shown below?

Accepted Answer

The compound has a 7-carbon chain and two halogens (bromine and chlorine) attached to carbons 4 and 2, respectively, and both on the same side of the chain. Therefore, the correct name is 4-bromo-2,2-dichloroheptane.

Question 10

What is the product of the hydrogenation of trans-2-pentene?

Accepted Answer

The product of the hydrogenation of trans-2-pentene is n-pentane. Hydrogenation adds hydrogen across the double bond, converting the alkene into an alkane with a straight chain, hence n-pentane.

Question 11

Accepted Answer

The answer of What is the name of the compound...

Question 12

Which of the following would be classified as organic? (i)HCOOH (ii)CO₃²^- (iii)CN^- (iv)CH₄ (v)CH₃OH

Accepted Answer

Organic compounds are primarily composed of carbon and hydrogen. HCOOH (formic acid), CH4 (methane), and CH3OH (methanol) are organic compounds. CO3^2- (carbonate ion) and CN^- (cyanide ion) are not typically classified as organic.

Question 13

Consider the following basic structure.  This structure is characteristic of all the carbon atoms found in which of the following classifications of hydrocarbons?

Accepted Answer

The given structure represents the structure of a carbon atom found in both alkanes and cycloalkanes. The "TB" in the structure represents a tert-butyl group, which is commonly found in these two classifications of hydrocarbons. The structure does not match the characteristics of alkenes or alkynes, as they typically have double or triple bonds, respectively, between carbon atoms.

Question 14

Which of the following compounds are classified as alkenes? Assume that none of the compounds listed is a cycloalkane. (i)C₅H₁₀ (ii)C₇H₁₆ (iii)C₄H₈ (iv)C₁₀H₂₂ (v)CH₄

Accepted Answer

The answer of Which of the following compounds are classified...

Question 15

What are the IUPAC and common names for the alkene with the molecular formula C₂H₄? IUPAC name Common name

Accepted Answer

The molecular formula C₂H₄ corresponds to C2H2, which is the formula for ethyne or acetylene. The IUPAC name for this compound is ethyne, while the common name is acetylene. None of the other answer choices match the formula for this compound. Therefore, the best choice is D, ethene or ethylene, is a different alkene with the formula C2H4.

Question 19

Which of the following compounds is/are not classified as hydrocarbons? (i)C₁₀H₂₂ (ii)CH₃CH₂CH₂CH₃ (iii)CH₃CH₂OH (iv)CH₂O

Accepted Answer

Hydrocarbons are compounds that only contain hydrogen and carbon atoms. (i) C₁₀H₂₂ - This compound contains sulfur (S) atoms, so it is not a hydrocarbon. (ii) CH₃CH₂CH₂CH₃ - This compound only contains carbon (C) and hydrogen (H) atoms, so it is a hydrocarbon. (iii) CH₃CH₂OH - This compound contains oxygen (O) atoms, so it is not a hydrocarbon. (iv) CH₂O - This compound contains oxygen (O) atoms, so it is not a hydrocarbon.

Question 20

A certain compound is a gas at room temperature and undergoes only substitution reactions.Which of the following is most likely to be this compound?

Accepted Answer

The compound must be a gas at room temperature, which means it must have a relatively low boiling point. The only option with a low enough boiling point is A, which has a boiling point of -44 degrees Celsius. Additionally, the compound must only undergo substitution reactions, which is not indicated in the chemical formulas provided.
