Explain the following observations:
(i) Generally there is an increase in density of elements from titanium (Z = 22) to copper (z =29) in the first series of transition elements.
(ii) Transition elements and their compounds are generally found to be good catalysts in chemical reactions.
How does it help in stabilising a structure Ans) More alpha hydrogens more hyper conjugations More hyper conjugation more is the stability Less inductive effect more hyper

Q. Reactions with metals? Ans. Halogens commonly undergo reactions with metals. Halogens react with the alkali metal family, Group IA in the periodic table. For example,
Which set of quantum numbers for an electron of an atom is not possible: (1) n=1 l=0, m=-0, s= +1/2 (2) n=1, l=1, m=-1, s= +1/2 (3) n=1, l=0, m=0, s= -1/2 (4) n=
what is molality?
Initially 5 mol of an ideal gas with Cv,m=12.5 J K^-1 mol^-1 are at a volume of 5 dm^3 and a temperature of 300K. If the gas is heated to 373 K and the volume changed to 10 dm^3, w
Q. Explain Ionization Energy? Ans. When an electron is removed from an atom, the atom has been ionized. Therefore, the energy required to remove an electron from an atom i
