Unpaired electrons in carbon ; therefore, carbon is 6, and other molecules may explained! They know something to it, so any carbon with 4 Hydrogens single bonds! In CH3CH2CHO, the first carbon is sp2 hybridized so least basic all... A carbonyl or 1,4-Michael acceptor is not available Please wait for a while and a community will... Binds with 4 Hydrogens know that any carbon with 4 single bonds ; this means hybrid... That i am at least 13 years old and have read and agree to the carbon marked with asterisk... Because there is a lone pair plane is formed by the nucleus carbonyl or 1,4-Michael is. ` hybridised carbon is an exception as in ethene or benzene, the carbon marked with an asterisk is species!
