Question

Draw the structure of Methyl hemiacetal of formaldehyde.

Answer 1

A hemiacetal is a compound that contains both alcohol and ether and is attached to the same carbon. Hydrogen occupies the fourth bonding position. An aldehyde is used to make a hemiacetal. A hemiketal is a compound that contains an alcohol and an ether, as well as two other carbons.

Complete answer:
A hemiacetal is a compound that contains both alcohol and ether and is attached to the same carbon. Hydrogen occupies the fourth bonding position. An aldehyde is used to make a hemiacetal. A hemiketal is a compound that contains an alcohol and an ether, as well as two other carbons.
HCHO is the formula for formaldehyde, a naturally occurring organic compound. The pure compound is a pungent-smelling colourless gas that naturally polymerizes into paraformaldehyde, so it's held in an aqueous solution. It is the most simple of aldehydes.

The methyl hemiacetal of formaldehyde would have a single C-atom in the centre of its structure.
Place four bonds around the C-atom after that.
Then add an H-H atom to the two bonds.
So, on the row third, add an OH atom.
Then $OC{H_3}$ will be attached on the last one.
