Why do transition elements show variable oxidation states ?

Posted by Krish Gupta 3 days, 13 hours ago

Sharan Dasari 2 days, 18 hours ago

Transition elements show variable oxidation states because the energy between their valency orbitals {(n-1)d and ns} is very less. So the both the energy levels can be used for bond formation.

Vp Raghavi 5 days, 17 hours ago

The last electron of zn is filled in d orbital were it has fully filled d orbital 3d^10 4s^2 ,the transition element means it has valence electron but zinc is fully filled so it is not a transition element.

Zn is fully filled in last d orbital they are electronic configurations is 3d^104s^2 they are stable in common oxidation state and transition element mean a half filled in d orbital is know as transition element

Zn has fully fill d orbital present in there d subshell there electronic configuration is 3d^10 4s^2 so and transition elements means a half filled d orbital is known as transition elements. Hope it will!

Adithya Dev 3 weeks, 2 days ago

Molarity = W 2 × 1000 / M 2 × V = 9.8 × 1000 / (137 + 17 + 17) × 250 = 9.8 × 4 / 171 = 39.2 / 171 = 0.23 M. // Therefore, normality = Molarity × n-factor = 0.23 × 2 = 0.46 N. //

Formic acid is stronger than acetic acid.

1 answers

Adithya Dev 1 month, 1 week ago

The main reason for stability of carboxylate anion formed by acidic property of carboxylic acids is resonance. But, even under such stability there does exist a possibility that the carboxylic carbon have some residual deficit of negative charge (not actually positive charge) , and this may be caused by the +I effect of alkyl groups connected to the carbon. But, since formic acid has no alkyl group connected to the acid group, it is the stronger than acetic acid.

Hello

Adithya Dev 1 month, 1 week ago

Chemically, an amino acid is a substituted methane molecule wherein three of the hydrogens around the central carbon are replaced by an amino group, an acid group and an alkyl group. Whether an amino acid is actually acidic, basic or neutral depends on the alkyl group. If the alkyl group has an amino substituent branch, the amino acid is basic, if the group has a - COOH substituent, the amino acid is acidic and if it has no other functional group, the amino acid is neutral. These amino acids undergo polymerisation to form heteropolymers known as proteins.
