# If sucrose is treated with concentrated sulphuric acid, the product formed is

$\begin{array}{1 1}(a)\;CO_2&\\(b)\;C\\(c)\;CH_4\\(d)\;CO\end{array}$

Solution :
It depends greatly on the concentration of the sulphuric acid…
Since sucrose is a disaccharide, hot dilute sulphuric acid catalyses the hydrolysis of sucrose into a mixture of glucose and fructose according to the following equation;-
However, if concentrated (98%) sulphuric acid is used, the reaction is firstly dehydration of the sucrose to give carbon;-
