Question

Where should the clamp be placed on the condenser in a Grignard reaction?

a) Top
b) Middle
c) Bottom
d) Anywhere along the condenser

Answer 1

In a Grignard reaction, the clamp should be placed in the middle of the condenser, generally closer to the top, to allow for effective cooling and to securely support the apparatus.

Step-by-step explanation:

The clamp should be placed in the middle of the condenser, but generally closer to the top during a Grignard reaction. This is done to provide support and hold the condenser securely while still allowing sufficient room for the cooling medium usually water or a cooling liquid, to flow effectively through it. This prevents the condenser from becoming too hot, which is critical since the purpose of the condenser is to condense any gases or vapors back into the liquid phase during the reaction.
