Read the passage given below and answer the following questions:

Alcohols are versatile compounds. They act both as nucleophiles and electrophiles. The bond between O-H is broken when alcohols act as nucleophiles.
(i) Alcohols as nucleophiles
(ii) The bond between C-O is broken when they act as, electrophiles. Protonated alcohols react in this manner.
Protonated alcohols as electrophiles
R-CH2-OH+H→R-CH2+OH2
Based on the cleavage of O-H and C-O bonds, the reaction of alcohols and phenols may be divided into two groups :
(a) Reactions involving cleavage of O-H bond
(b) Reactions involving cleavage of C-O bond
Acidity of alcohols and phenols
(i) Reaction with metals :Alcohols and phenols react with active metals such as sodium, potassium and aluminium to yield corresponding alkoxide/ phenoxides and hydrogen.

 
Q. Write down the decreasing order of reactivity of sodium metal towards primary, secondary and tertiary alcohols.
  • a)
    1oalc<2oalc<3oalc
  • b)
    1oalc>2oalc>3oalc
  • c)
    3oalc<1oalc<2oalc
  • d)
    3oalc>Ioalc < 2oalco
Correct answer is option 'B'. Can you explain this answer?

Na metal is basic and alcohols are acidic in nature. Hence, reactivity of Na metal towards alcohols decreases as the acidic strength of alcohols decreases due to steric hinderance of alkyl groups in tertiary alcohol and increase in electron density on an oxygen atom in the hydroxyl bond.
