Answer 2

Reduction of ketones by Sodium Borohydride or Lithium aluminumhydride gives:

B. Secondary alcohol

Explanation:

Reduction of ketones by Sodium Borohydride or Lithium aluminumhydride gives: Secondary alcohol.

• Reduction of  Ketones produces secondary alcohols.

• Lithium Aluminumhydride and Sodium Borohydrides are reducing agents and act on the compound to reduce it.

• Lithium Alminumhydride is a much stronger reducing agent when compared to Sodium borohydride but both these agents reduce ketones to Secondary alcohols.
• Aldehydes and Ketones readily  react with hydrides to be reduced. Aldehydes on reduction produce primary alcohols and Ketones reduce into secondary alcohols.
• An acid-base reaction, acidic workup takes place to convert the intermediate metal alkoxides  into alcohols.
• Secondary alcohols are have the hydroxyl group on the second Carbon atom, bonded by two other carbon atoms.
