Question: What is the major product of the following reaction: CH3Br + NaOH (ethanol)?

Options:

Correct Answer: CH3OH

Solution:

The reaction is an SN2 substitution where the nucleophile (OH-) attacks the carbon bonded to Br, resulting in the formation of CH3OH.

What is the major product of the following reaction: CH3Br + NaOH (ethanol)?

What is the major product of the following reaction: CH3Br + NaOH (ethanol)?

Step 1: Identify the reactants. We have CH3Br (methyl bromide) and NaOH (sodium hydroxide) in ethanol.
Step 2: Recognize that NaOH provides OH- (hydroxide ion), which acts as a nucleophile.
Step 3: Understand that in an SN2 reaction, the nucleophile (OH-) will attack the carbon atom that is bonded to the bromine (Br) in CH3Br.
Step 4: The Br atom is a good leaving group, so when OH- attacks the carbon, Br leaves, and we form a new bond between the carbon and the OH group.
Step 5: The product formed is CH3OH (methanol), as the Br is replaced by the OH group.
