An alkene on ozonolysis gave acetone and ethanal.The alkene is
(A) 2 - butene
(B) 2 - methyl -1 - butene
(C) 2 - methyl - 2 - butene
(D) 1 -butene

An alkene on reductive ozonolysis produce two moles of ethanal. Then the alkene is (A) 2 - butene (B) Ethene (C) Propene (D) 1 - butene

3,3-dimethyl-1-butene

2-ethyl-3-methyl-1-butene

4-chloro-2-ethyl 1-butene

2-Methyl-2-butene will be represented as

The decreasing order of reactivity of the following alkenes is: i. 2, 3 -Dimethyl- 2 butene ii. 2 - Methyl- 2 butene 2 - Butene iv. Ethane

Correct order of stability is (A) Cis-2-butene > 1 - butene > trans - 2 - butene (B) trans--2-butane > cis-2-butene > 1 - butene (C) 1 - butene > Cis-2-butane > trans- 2 - butene (D) cis-2-butene > trans -2- butene > 1- butene А

Which among the following compounds show geometrical isomerism (I) 1-butene (II)2-butene (III) 2-methyl-2-butene (IV) 2-pentene

(a) Give the decreasing order of stabilities of the following alkenes : (i) Ethene, (ii) Propene, (iii) cis-2- butene (iv) trans-2-Butene (v) 2- Methy1-2-butene, (vi) 2,3- Dimethy1-2-butene (b) Give the decreasing order of reactivity of the above alkenes. ( c) Give the product of the following reaction : Me_(2)CHCH_(2)CH_(2)OH overset("Dehydration")underset("Conc"H_(2)SO_(4)(160-170^(@)C))rarrunderset(-H_(2)O)(A)
