If CH2OH is a substituent of the parent carbon chain, what will be it's name

Answer 1

When CH₂OH is a substituent of the parent carbon chain, it is referred to as a "hydroxymethyl" group. This is because CH₂OH contains a hydroxyl (-OH) group attached to a carbon (specifically, the carbon is also bonded to two hydrogen atoms). Therefore, in the context of organic chemistry, you would name this substituent as "hydroxymethyl." For example, if CH₂OH is attached to a longer carbon chain, you would specify the location of the hydroxymethyl group in the full name of the compound.
