ORGANIC!!

tapan it was to prov that double bonds reacts faster than triple as unstable vinyl cation is formed
( that i showed in the fig)

but also in Q 1 H⁺ still attacks triple bond such that overall stability is not disturbed

first the compound was stable due to conjugation hence for the product to remain in conjugation H⁺ attacks triple bond

always consider overall stability of compound first

Vish : My dbt in Q1 is not werther duble or tripl bond is attacked........ that's triple 4 sure

Ther two Carbons mutually triply bonded......... extreme rite wala n the one next to it.....

Now Cl will go to wich C out of the two is ma DOUBT,.......

hey dat is bcoz of greater stability of the carbocation !!!

vishal cud u plz explain things a bit more clearly

after addition of H⁺

CC-----C⁺c----H ( charge is conjugated)

and

CC-----Cc⁺----H ( charge is not conjugated)

r possible

clearly 1st carbocation is more stable than 2nd due to conjugation with double

bond hence Cl^- will bond with 1st structure

thanks wud u also explain 2nd one

richa 2nd one is easy simply on the facts that

1. double bonds are more reactive than triple

2. 2⁰ carbocation is more stable than 1⁰ carbocation

low temp hmm its exothermic reaction naa ( and i think highly isothermic maybee)

so low temp will provide slow rate of formation ( or kindof correct rate if its highly exothermic)

something like this [4][4]

@tapan a possible explanation for 1:
a stable alkene forms as it becomes conjugated... but i dont think that applies for 2nd one then :(

nd wat happens at high temp....

at high both thebonds are attacked

well use two concepts here
1. in general duble bonds r more readily attacked than triple ( this explains for 2)

2. conjugated alkene is more stable so in 1 rather triple bond is attacked so such that the conjugation is not disturbed

how can both bond b attacked wen 1 equivalent is given

k for 1 eq u r asking

k then the same products will be formed [4]

y can u xplain plz??

bt dis carbon z sp hybridised naaa
