Role-specific Inorganic Chemistry Interview Questions & Answers:

1. Explain A catalyst?

(a)always slows down the reaction
(b)always starts a rection that would not have ocurred at
all otherwise
(c)causes changes in the rate of the reaction
(d)changes the quantities of the products formed

3. Why we use sulphuric acid in the experiment of measure absorpance of K2Cr2O7 and KMnO4?

In case of Dichromate we use it to maintain the pH, otherwise
there is a mixture of Chromate and Dichromate. They donot
absorb at the same wavelength. So we cannot use Lambert-Beer's
Law.
For permanganate use of sulphuric acid is not for this reason
but to maintain the pH as in neutral or alkaline solution
permanganate get hydrolyzed to for manganese dioxide.

5. What is the inorganic chemistry?

Inorganic is a branch of chemistry that deals with the
properties and behavior of inorganic compounds

6. Why lead acetate s used in the Limit test of Arsenic?
What role Lead Acetate plays?

During limit test for As, Zn & conc HCl is used. if H2S formed the reaction with Lead Acetate gives lead sulphide.If it is not used then it reacts with mercuric bromide gives yellow stain.

7. What is the basics of electronic spectroscopy?

The electronic transition between ground state and the
excited state in terms of energy

8. Out of (CH3)3C- and (CH3)2CH- carboanion, which is more stable and why?

(CH3)2CH- because neighbouring protons stabilise a negative charge better than neighbouring carbon. (The neighbouring C-H sigma bonds have an overlap of electron density with the lone pair in the p-orbital, which is destabilising.)

9. Give the IUPAC name.
i) [Co(NH3)5SO4]Cl
ii) [Co(NH3)5Cl] SO4
iii) [CoCl.CN.NO2.(NH3)3]

1). PENTAAMINE SULPHATOCOBALT III CHLORIDE
2). PENTAAMMINE CHLOROCOBALTIII SULPHATE
3). TRIAMMINECHLORONITROCOBALTIII

10. Who is the father of chemistry?

LAVOSIER
Because,he defined law of chemical reaction
