Question

In petrochemical industry, any petroleum fraction having an approximate boiling point range between 20°C and 200°C which is used as a feed stock is called:

• A. kerosene
• B. gas oil
• C. naphtha
• D. LPG

Hint:

Naphtha is commonly used in the petrochemical industry for cracking and as a feedstock for producing various chemicals.

Answer 1

The Correct Option is C

Step 1: Understanding feedstock in the petrochemical industry.
Naphtha is a petroleum fraction with a boiling range between 20°C and 200°C, making it suitable as a feedstock for various petrochemical processes, including cracking.

Step 2: Explanation of options.
- (C) Naphtha is the correct feedstock with the given boiling range. - (A) Kerosene has a higher boiling point and is not typically used in cracking. - (B) Gas oil is a heavier fraction than naphtha. - (D) LPG has a boiling point below 20°C.

Final Answer: \[ \boxed{\text{C) naphtha}} \]
