Question

sapling llearning Pamela Mills at City University of New York (CUNY), Hunter Colle Alkanes have free rotation around the carbon-carbon single bonds. That is, two groups of atoms joined by a carbon-carbon single bond can rotate with respect to each other around the bond. Therefore, alkanes can exist in different conformations. Consider the two alkanes below and answer the questions asked. C4 What is the chemical formula of A C1 C2 and B C3 Molecule B can be obtained from molecule A by rotating around O C2-C3 molecule O C1-C2 which bond: O O C3-C4 not the same molecules

Explanation / Answer

chemical formula of A and B: CH3CH2CH2CH3

molecule B can be obtained from molecule A by rotating around C2 - C3 bond
