Answer:

b) hydrocarbon??

Explanation:

is it right

Answer 2

Option b is the right answer. An aldehyde when warmed with Zn/Hg and conc. HCl gives hydrocarbon.

• The reaction of an aldehyde with Zn/Hg and conc. HCl is known as Clemenson reduction.
• The reaction is named after a Danish Chemist Erick Christian Clemenson.
• Clemenson reaction is used to reduce aldehydes or ketones into hydrocarbons using hydrochloric acid and zinc amalgam.
• It is highly effective in reducing aryl-alkyl ketones.
• Carbanionic and carbenoid mechanisms are suggested for this reaction.
• The substrates of the reactions should be stable under very high acidic conditions of this reaction.
