AIEEEE'S INORGANIC SHELL

Q7. MgCl₂
Q1. b

Asish,did a basic mistake in Q.7. LiCl imparts crimson red colour to the flame.
and,ya u r right in Q.1,but please provide explanation

1) IN TERMS OF POLAR CHARACTER, WHICH OF THE FOLLOWING ORDER IS CORRECT ?

A. NH₃ < H₂O < HF < H₂S

B. H₂S < NH₃ < H₂O < HF

C. H₂O < NH₃ < H₂S < HF

D. HF < H₂O < NH₃ < H₂S

@aieee : Plz hide the qs answered or Bold them to avoid confusion :)

9) A

10)B

Sure ones ---
2. C
3. D
4. D
6. B

1) ans. b is right
. 2) it's obviously c) ( which all of u hv done)
3) it hs become a common question. its rightly d).
4) also , right. d)
5) govind , u r right. but, cn u explain it ?
6) rightly b).
7) ans is a.
8) govind is right.
9) uttara, u r right. cn u say why ?
10) uttara , ur ans is not right.

so, i'm hiding all the questions done. try the rest.

i hv provided new questions, requiring explanations. so, start answering !

19) A good salt analysis problem :

A + heat → B (g) + C (l)

B is used as a propellant in ice-creams and reacts with NaNH₂ to form gas D.

C + FeCl₃ → yellow-brown lumps of a compound E.

A + NOCl → an acidic salt F + G ( a colourless solvent )

G forms a mixture of two acids with water.

One of the acids decompose to give a reddish brown gas and a gas H along with C.

Find A to H.

@aieee
can u plz give some more hints for the above problem
