another

Englishman,

Greville

Williams, heated some rubber and obtained a colourless liquid that he called isoperene. Each isoperene molecule contains five carbon atoms and eight hydrogen atoms (C5H8).

Three hydrogen atoms surround the fifth carbon atom to form a methyl group. : www.indiandentalacademy.com
