PHBV is a biodegradable copolymer composed of two monomers, X and Y. Identify X and Y respectively.
- 1X = C2H5-CH(OH)-CH2-COOH; Y = C2H5-CH(OH)-COOH
- 2X = CH3-CH(OH)-CH2-COOH; Y = C2H5-CH(OH)-CH2-COOH✓
- 3X = CH3-CH(OH)-CH2-OH; Y = C2H5-CH(OH)-CH2-COOH
- 4X = H2N-(CH2)5-COOH; Y = CH3-CH(OH)-CH2-COOH
Correct answer
X = CH3-CH(OH)-CH2-COOH; Y = C2H5-CH(OH)-CH2-COOH
