Yup. Its the C which has max no of substituents.
The quality of a person's life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.

It is during our darkest moments that we must focus to see the light.

aree i think susbtituited implies no of groups surrounding a cabon,,,,,

i mean it is less sustituited when the groups attached to it r as small as hydrogen
and it is highly susbtituited when the attached froups are heavy like propyl , phenyl etc........
this word is so small that it is a foolishness to hate anyone.
so, we love all.
