b
wolf kisshner does its work and then in basic medium, alyl halide undergoes E2
Cant be clemmenson as it includes acidic medium which would break cyclic acetal
ans is b
Tollens works on hemiacetals but not acetals
Al releases e- which form Ketyl anion
The radical goes on the 2 degree carbon
two such ketyls combine to form b
in the trimethyl orthoformate, h+ attacks the oxygens and forms ch3oh and +ve charge on C. then water attacks and we get an OH on the C
This repeats 3 times till we get 3ch3oh and c with 3 OH bonds which gets dehydrated to form formic acid
the ch3oh then react with the cyclic compound to form (b)
b as clemmenson mei H+ can attack the S and rhe O and break the ether bonds
HNO3 breaks the ring and form dicarboxylix (adipic acid) which after Caoh2 releases co3
ring contraction occurs and we get c
Methanal undergoes EAS on benzene as H+ attacks the o and makes the Carbon extra electron hungry
Agno2 reduces ald and adds NO2
c
When the peroxide link breaks, Oh- gets removed and so we’re left with O+.
to deal with this, the ring breaks and carbon gets -ve charge which then forms db with O
The carbocation formed gets attacked by water to get primary alc
Phenyl group always looks to stabilise the thing its attached to. so it can both take e- and give e-
in this case it gives e- and so hence ans is b
KH attacks on the alpha carbons as there, the -ve charge will be stable by reso
Then CH3I attacks and Ch3 gets attatched
Since everything is in excess, this repeats twice
A
this is because lower steric hinderance means greater nucleophilicty
Kmno4 oxidises and then h2o opens the diol
Aldehyde is formed in B
The leftmost N of the reagent attacks the aldehyde as its the most basic as it doesnt resonate and lose its electrons to the oxygen
hence ans is a
gives positive iodoform
has a carbonly group as its being removed by NaHSo3
hence ans is b
form ald
attack on ald
gives H+ to remove the grig ka doosra part
turns ester to acod
The secondary alc attacks on anhydride
grig forms and attacks on methanal
the acid both removes the grig and hydrolyses the acetal
ans is c
then hydrolyse the imine (just remove the db N and get an O in its place)
Ald>keto
you can make the order yourself now
Beckman rearrangement forms amide
