Question

PHBV contains two kinds of repeat units: -[O-CH(CH3)-CH2-CO]- (HB, C4H6O2) and -[O-CH(C2H5)-CH2-CO]- (HV, C5H8O2). Which statements are correct (C 12, H 1, O 16)?

Accepted Answer

The HB unit has a molar mass of 86 g/mol.

Accepted Answer

The HV unit has a molar mass of 100 g/mol.

Accepted Answer

A chain segment of 10 HB units and 5 HV units has a mass of 1360 g/mol (end groups neglected).

Answer

PHBV is formed by addition polymerisation of alkenes.

PHBV contains two kinds of repeat units: $- [O - CH (CH X_{3}) - CH X_{2} - CO] X^{-}$ (HB, $C X_{4} H X_{6} O X_{2}$ ) and $- [O - CH (C X_{2} H X_{5}) - CH X_{2} - CO] X^{-}$ (HV, $C X_{5} H X_{8} O X_{2}$ ). Which statements are correct (C 12, H 1, O 16)?

Answer: B, C, D
