Answer :
Below is a potential reaction product if you forgot to add the drying tube. The Grignard reagent reacts with (a) water to give the product, an alcohol
Without a drying tube, the Grignard reaction could react with moisture in the air, yielding a potential product like an alcohol. If water (a) is present, it would react with the Grignard reagent to form an alcohol. Grignard reagents are highly reactive towards water, leading to the generation of a metal hydroxide and an alkane.
So, this side reaction can decrease the yield of the desired product and potentially form unwanted byproducts. Thus, the absence of a drying tube can compromise the purity and efficiency of the Grignard reaction.
