Unformatted text preview: -in stable cmpd H can form only 1 bond at a time Simplest: CH 4 (methane) – mf. || sf. – drawing a) || 3-D Representation – drawing b) tetrahedral geometry Isomer: different molecules that have the same mf. Constitutional isomers (structural) – differs in bonding connectivity Condensed structural formula: CH 3 CH 2 CH 2 CH 3 (butane) CH 3 (CH 2 ) 2 (CH 3 ) 3 CH (isobutane)...
