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 CH CH2CH2C C1 C2 and B C3 Molecule B can be OC1-C2 C1C2 obtained from molecule A by rotating around which bond lac3 C3-C4 which bating around O O not the same molecules O Previous Give Up & View Solution Check Answer 0 N.. 8 Exit-t Hint

Explanation / Answer

SOLUTION

Molecular formula of B is same as that of A = C4H10 (CH3-CH2-CH2-CH3)

We can get molecule B from A by the rotation of C2-C3 bond
