Choose the correct answer from the options given below :
The incorrect method to synthesize benzaldehyde is
Given below are two statements :
Statement I : The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole - dipole interactions.
Statement II : The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of H-bonding.
In the light of the above statements, choose the most appropriate answer from the given below
RMgX + CO2 $$\mathrel{\mathop{\kern0pt\longrightarrow} \limits_{ether}^{dry}} $$ Y $$\buildrel {{H_3}{O^ + }} \over \longrightarrow $$ RCOOH
What is Y in the above reaction?
