Solution

Dear STudent,

The addition of oil in saponification reaction generates more heats by producing glycerol and solid soap as products and the reaction scheme is expressed below,

$G l y c e r o l T r i o l e a t e + 3 N a O H \to 3 C H_{3} (C H_{2})_{7} C H = C H (C H_{2})_{7} C O O N a (s o a p) + G l y c e r o l$
Hence the liquid X is Oil and Solid Y is soap.

Answer is Option (B) Oil, Soap

Regards.
