Homework Answers
Q NO 1. Difference of transition metal from main metal group is
- They have large charge/radius(q/e) ratio;
- They are hard and have high densities;
- It having high melting and boiling points;
- It form compounds which are often paramagnetic;
- It show variable oxidation states;
- It also form coloured ions and compounds;
- form compounds with profound catalytic activity;
Q NO 2.
ZINC is not considered as transition metal beacause because its compounds or ions (Zn2+) contain a full filled d-orbital or sub shell and are unstable.
Q No 3.
Electronic configuration of ions are given as under
Q No 4
Assumption are as under
• The interaction between central metal and legand is pure electrostatic in nature.
• The legand are treated as point charge.
•spliting of d orbital in certain ions complex
Q No 5
Because those compound are colourful which has valence electron in their orbit which means some it has to be paramagnetic but in above cases it can be determined by written electronic configuration of each Ti4+ and sc3+.
Q No 6
No of unparied electron in
[Cr(en)3]3+ is 3 because Cr is in +3 O.S. It has electronic configuration 3d3 4s0
Q.No 7 op
Spectrochemical series
It arranges the legand in a order of there ability to spilt in octahedral complex ion.
Q No.8
