a) benzophenone
b) formaldehyde
c) acetone
d) acetaldehyde
Acc to me the answers should be both b and d as both of these compounds give silver mirror test
2)Identify the compound that exhibits tautomerism.
a) Lactic acid
b) 2-Pentanone
c) Phenol
d) 2- Butene
In this case both b and c should be the answers
Further the answer of the following two questions in physics is yet undecided as it is given different in different solutions
1)This question has Statement – 1 and Statement – 2. Of the four choices given after the statements,
choose the one that best describes the two statements.
Statement-1 : Sky wave signals are used for long distance radio communication. These signals are in
general, less stable than ground wave signals.
Statement-2 : The state of ionosphere varies from hour to hour, day to day and season to season.
(1) Statement-1 is true, Statement-2 is true; Statement-2 is the correct explanation of Statement-1.
(2) Statement-1 is true, Statement-2 is true; Statement-2 is not the correct explanation of Statement-1.
(3) Statement-1 is false, Statement-2 is true.
(4) Statement-1 is true, Statement-2 is false.
2)
Direction:
The question has a paragraph followed by two statements, Statement – 1 and statement – 2. Of the
given four alternatives after the statements, choose the one that describes the statements.
A thin air film is formed by putting the convex surface of a plane – convex lens over a plane glass plate.
With monochromatic light, this film gives an interference pattern due to light reflected from the top
(convex) surface and the bottom (glass plate) surface of the film.
Statement-1 : When light reflects from the air-glass plate interface, the reflected wave suffers a phase
change of π.
Statement-2 : The centre of the interference pattern is dark.
(1) Statement-1 is true, Statement-2 is true; Statement-2 is the correct explanation of Statement-1.
(2) Statement-1 is true, Statement-2 is true; Statement-2 is not the correct explanation of Statement-1.
(3) Statement-1 is false, Statement-2 is true. (4) Statement-1 is true, Statement-2 is false.

d paper makers are just u knw
phele iit k paper mein do galat
phir paper leak
aur abh isme do galat dal rakhe hein
bacho ke bhavise k sath khel rahe hein woh
right dude
I CANT DO MUCH ABT IT
WHATEVER
kya hamara life ka future is just rs 6lakh??? yaar itni mehnet karo n see mtlab ab corruption hame bhi kha rha hai.... we wnt justice... what say??
hey guies
was the second paper easy
