Ans 1.. Eclipsed structure will be the most stable one due to hydrogen bonding
Ans 2 .. C the alkyl groups on the ortho postion change the plane of nitrogen due to which the lone pair of nitrogen do not resonate with the pie electrons of the ring.
Ans 3.. i think the answer shud be A
1..WHICH CONFORMATION OF ETHYLENE GLYCOL IS MOST STABLE;
(1)STAGGERED (2)GAUCHE
(3)ANTI (4)ECLIPSED

agree with govind ...for 1 and 2....
but for 3....i think its 'd' tho i dont ve apt reason

Hey Rocky r u sure that answer of qn. 1 is c..
coz i remember that in case of glycol..there is hydrogen bonding..
so either gauche or staggered will be stable...

yeah answer to 1 will be (3) only......
it will have intermolecular hydrogen bonding....
