Answer 1

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the concept of General organic chemistry.

1.) The formula for alkanes is Cn H2n+2

===> here n = 500, hence we get as,

C500, 2n+2 = 2(500)+2 ==> 1000+2 ==> 1002

hence the formula is ==> C500 H1002

2.) The formula for alkenes is,

CnH2n

hence, here n = 15

so we get as,

===> C15 H30
