When O-H bond breaks in alcohol is the order of reactivity
Correct answer: B. Methyl alcohol > primary alcohol > secondary alcohol > tertiary alcohol
- A. Primary alcohol > secondary alcohol > tertiary alcohol
- B. Methyl alcohol > primary alcohol > secondary alcohol > tertiary alcohol
- C. Primary alcohol < secondary alcohol < tertiary alcohol
- D. Ethanol > primary alcohol > secondary alcohol > tertiary alcohol
Explanation
This option is correct because it shows the correct order of reactivity of alcohol when O-H bond break. According to this methyl alcohol are more reactive because when O-H bond breaks down methoxide. (alkoxide) is formed. This methoxide is very unstable and immediately gains stability. Thus in this order tertiary alcohol are the most stable.Methyl alcohol-primary alcohol-secondary alcohol> tertiary alcohol.

About Alcohols
Alcohols contain a hydroxyl group attached to a saturated carbon atom and are classified as primary, secondary or tertiary. Their nomenclature, hydrogen bonding, acidity, oxidation, dehydration, reaction with sodium and conversion to haloalkanes are covered, along with the distinction between alcohols and phenols, where the hydroxyl group is attached directly to an aromatic ring.
