Question 1

The geometry of a carbonyl is ___ .&#10;A) Tetrahedral&#10;B) Trigonal Planar&#10;C) Trigonal Pyrimidal&#10;D) Linear&#10;E) Bent

Accepted Answer

The carbonyl group (C=O) has a trigonal planar geometry due to the sp2 hybridization of the carbon atom, which forms a planar structure with 120-degree bond angles.

Question 2

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III&#10;D) IV

Accepted Answer

Reduction with sodium borohydride reduces only the ketone, not the acid.

Question 3

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III&#10;D) IV

Accepted Answer

Reduction with lithium aluminum hydride reduces the ketone to a secondary alcohol and the ester to a primary alcohol.

Question 4

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III&#10;D) IV

Accepted Answer

Reduction with lithium aluminum hydride reduces the ketone to a secondary alcohol and the carboxylic acid to a primary alcohol.

Question 5

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III&#10;D) IV

Accepted Answer

Reduction with sodium borohydride reduces only the aldehyde, not the ester.

Question 6

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III&#10;D) IV

Accepted Answer

Oxidation with PCC oxidizes primary alcohols to aldehydes and secondary alcohols to ketones.

Question 7

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III&#10;D) IV

Accepted Answer

Oxidation with chromic acid turns primary alcohols into acids and secondary alcohols into ketones.

Question 8

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III&#10;D) IV

Accepted Answer

Grignard reagents reduce ketones to alcohols while adding the alkyl group once.

Question 9

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III

Accepted Answer

Grignard reagents react twice with esters to form a tertiary alcohol and adds two equivalents of the alkyl group.

Question 10

What is the product of the following reaction?  &#10;A) I&#10;B) II&#10;C) III&#10;D) IV

Accepted Answer

Organolithium reagents reduce ketones to alcohols while adding the alkyl group once.
