Options

1. ASecondary and tertiary alcohols are less reactive than primary alcohols.
2. BSecondary and tertiary alcohols are more prone to oxidation during the reaction.
3. CEthers are formed as a result of acid dehydration by S N 2 mechanism from primary alcohols.If secondary or ter
4. DSecondary and tertiary alcohols form unstable intermediates in this process.
