naphthalene is a non polar substance so it will dissolve in non poalr solvent and camphor pon the other hand will dissolve in polar solvent.what do mean by polar here...???

answered-by-expert Expert Answer
Camphor is polar because it contans ketone in its structure which makes it polar(due to the lone pairs of electrons present on oxygen).Whereas in case of naphthalene C - H atoms show an electronegativity difference of 0.4, thus this is treated as slightly polar bond. But concerning the structure of naphtalene (two benzene rings), it is a very stable molecule and won't dissolve easily in water - thus it behaves mostly unpolar.
