  • Solution

Phenylmethyl ketonecan be converted into ethylbenzene inone step by which of the following reagents?

  • Solution

In the reaction

  • Solution

(CH3)3C–CHO does not undergo Aldol condensation due to

  • Solution

    Aldol condensation is given by the compounds which contain α hydrogen atom. As the given compound does not contain α hydrogen atom. Hence it does not undergo aldol condensation.
