EMO123:
What word describes the petrochemical industry process of converting straight chain alkanes into cycloalkanes, cycloalkenes and aromatics?
HUSH1994:
is is someone in this article:

red_911:
which one of these have higher boiling point: alkanes, alkenes, carboxylic acids or halogenoalkanes ... explain all a little please ???
EMO123:
i think you should read it from your book it is fully explained

It depends on the intermolecular forces between the molecules, which are Van-der-waals, permanent dipole-dipole and hydrogen bonds( type of Perm. Dipole-Dipole).
Strength of Hydrogen bonds>permanent dipoles>van-der-waals.
As electrons increase, van-der-waals increase since they are actually induced dipoles from the movement of e's.
Hydrogen bonds form between N,O,F lone pair and H.
So if you are talking abt corresponding alkanes<alkenes<alchohols<carboxylic acids. Ofcourse as Carbon atoms increase m.p and b.p increases!
