Question

Write the molecular formula of third and fifth member of alkane and alkyne group

Answer 1

For ALKANE,
General formula of alkane is CnH2n+2,where n=1,2,3,.....
So , C3H8(propane)[Alkane third member]
C5H12(pentane)[Alkane fifth member]
again,
For ALKYNE,
Gen.formula of alkyne is CnH2n-2,where n=3,4,5..........
C3H4(Propyne)[Alkyne third member]
C5H8(Pentyne)[Alkyne fifth member].

Answer 2

Answer:

For ALKANE,

General formula of alkane is CnH2n+2,where n=1,2,3,.....

So , C3H8(propane)[Alkane third member]

C5H12(pentane)[Alkane fifth member]

again,

For ALKYNE,

Gen.formula of alkyne is CnH2n-2,where n=3,4,5..........

C3H4(Propyne)[Alkyne third member]

C5H8(Pentyne)[Alkyne fifth member].
