What is the structural difference between HDP and LDP? How does the structure account for different behaviour and nature, hence the use of a polymer?
Options
- ALDP (low-density polymer) consists of a linear molecule and has a high density due to close packing. It is qui
- BHDP (high-density polymer) consists of a linear molecule and has a high density due to close packing. It is qu
- CHDP has a crystalline structure, while LDP has an amorphous structure.
- DHDP has a higher molecular weight, while LDP has a lower molecular weight.
Correct answer
B. HDP (high-density polymer) consists of a linear molecule and has a high density due to close packing. It is qu
Step-by-step solution
Correct Option is : (B) HDP (high-density polymer) consists of a linear molecule and has a high density due to close packing. It is quite hard, tougher and has greater tensile strength than LDP. The LDP (low-density polymer) has a highly branched structure. Due to branching, the molecules do not pack well.
