What is the name of this compound? see attached.

a) phenylhyde

b) benzaldehyde

c) phenol aldehyde

d) cyclohexylhyde

Option (b) is the correct answer.

Explanation:

In the given structure a benzene molecule, that is, is attached. And, further an aldehyde group that is, CHO group is attached to the benzene molecule.

Hence, suffix "aldehyde" will be added to the name of this molecule.

Whereas a group with formula is known as phenol.

Therefore, we can conclude that the name of this given compound is benzaldehyde.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

the answer would be a
