How will u distinguish between??
1)propene and propane
2)1-butene and 1-butyne
3)2-butene and 2-butyne
4)formaldehyde and acetaldehyde
1) Differ by the presence of the double bond (in the reaction with potassium permanganate propene discolors it) 2) The first carbon atom in butene - 1 has double bond,...

Reaction of 1,3- butadiene to maleic acid gives cis product while fumaric acid
gives trans product
First of all, for my opinion it isn`t correct question.From 1,3- butadiene by oxidation we can formate maleic anhydride. In industry, maleic acid is derived by hydrolysis of maleic anhydride....

9. Which compound would show optical activity?
A) cis 1, 4- dimethylcyclohexane
B) trans 1, 4- dimethylcyclohexane
C) cis 1,4- dimethylcycloheptane
D) trans 1, 4- dimethylcycloheptane
Answer Should Be "C" . cis 1,4- dimethylcycloheptane .Optical activity is the ability of a chiral molecule to rotate the plane of plane-polairsed light, measured using a polarimeter. A simple polarimeter...

c) Explain using structures why trans-2-Butene (a disubstituted alkene) is more stable than cis-2-butene (another disubstituted alkene)?
The stability of an alkene can be determined by measuring the amount of energy associated with the hydrogenation of the molecule. Since the double bond is breaking in this reaction,...

Show how you would accomplish the following conversions.
1.cis-hex-3-ene to (d,l)-hexane-3,4-diol
2.trans-hex-3-ene to meso-hexane-3,4-diol 3.trans-hex-3-ene to (d,l)-hexane-3,4-diol
1..cis-hex-3-ene to (d,l)-hexane-3,4-diolFor Above Conversion We Use " KMnO4( aq) / LOW Temperature ." 2..trans-hex-3-ene to meso-hexane-3,4-diolFor Above Conversion We Use " KMnO4( aq) / LOW Temperature ." 3..trans-hex-3-ene to...
