Ethene means it has two carbon atoms in it.but we know,alkene must contain double bond at least for once somewhere in the carbon chain.But hydrogen atoms dont form double bonds.so methene can't be the 1st member bcoz it can't formdouble bonds as there is no other carbon and only hydrogn atoms.so,ethene is the 1st member where it can form one carbon carbon doble bond with the two carbon atoms present.and there is no such thing as methene,i suppose.....
