acetylene
ethene
2-butyne
2-butyne
C.
2-butyne
The reaction is 
The order of stability of the following carbocations,
III>II>I
II> III>I
I>II>III
I>II>III

An unknown alcohol is treated with the “Lucas reagent” to determine whether the alcohol is primary, secondary or tertiary. Which alcohol reacts fastest and by what mechanism
Secondary alcohol by SN1
Tertiary alcohol by SN1
Secondary alcohol by SN2
Secondary alcohol by SN2
B.
Tertiary alcohol by SN1
Reaction proceeds through carbocation formation as 30 carbocation is highly stable, hence reaction proceeds through SN1 with 30 alcohol.
What is DDT among the following
Greenhouse gas
A fertilizer
Biodegradable pollutant
Biodegradable pollutant
D.
Biodegradable pollutant
DDT is P,P' - Dichlorodiphenyl trichloro ethane. It was used as an insecticide. DDT is not metabolised very rapidly by animals. It was also discovered to have a high toxicity towards fish. Therefore, It is a non-bio degradable pollutant.
