Question

MOLECULAR FORMULA--------​

Answer 1

Ethane = C2 H6

Propene = c3 H8

Butene =C4 H10

Pentene =C5 H12

Hexene =C6 H14

Explanation:

For chemical with sufix - ene use 2n+n

" " - ane use 2n

" " - yne yne 2n-n

Wher n is the no of carbon

The above formula are for hydrogen

And for carbon use Cn for all three

Answer 2

Answer:

Ethene = C2H4   Propene=C3H6   Butene=C4H8   Pentene=C5H10   Hexene=C6H12

Explanation: Empherical Formula of compound with suffix ene is CnH2n

and Meth=1 carbon Eth = 2C Prop=3C But=4C Pent=5C Hex=6C

and suffix ene means double bond
