Actually as at higher altitude atmospheric pressure is less so boiling point is less. As boiling point is the temperature when vapour pressure of water is equal the atmospheric pressure so as atmospheric pressure decrease so boiling point also decreases.

The freezing point is the temp. At which liquid or solid solvent at equilibrium so , their vapour pressures are equal. When non-volatile solute added to volatile liquid solvent solution , vapour pressure lower than that of pure solvent.

Sia ? 6 years, 7 months ago

N₁V_{1 =}N₂V₂(N = Normality, V = Volume)

n₁M₁V₁= n₂M₂V₂(n = valence factory, M = Molarity)

For H2SO₄, n₁=2, M₁=0.1

For NaOH, n₂=1, M2=0.2,V₂=0.03

2 x 0.1 x V₁= 1 x 0.2 x 0.03

V₁= (1 x 0.2 x 0.03) / (2 x 0.1)

= 0.006 / 0.2

= 0.03

So, volume of H_sSO₄is 0.03 L or 30mL

What is nucleophilic reaction

Posted by Golden Hayong 6 years, 7 months ago

CBSE > Class 12 > Chemistry

1 answers

Gaurav Seth 6 years, 7 months ago

Nucleophilic Substitution Reaction : A chemical reaction in which a stronger nucleophilic (electron rich group which loves +ve centre) substitutes a weaker nucleophile is called the nucleophilic substitution reaction. For example, CH₃Br + OH→ CH₃OH + Br is a nucleophilic substitution reaction.

In haloalkanes (R—X) the halogen is more electronegative than carbon. Thus, C—X bond is polarized as C⁺—X^-. Therefore, a strong nucleophile (electron rich species) such as Z attacks the positively charged carbon atom and replaces weak nucleophile halogen from C—Z. Thus a new product is formed.

What is geometrical and optical isomerism (co-ordination compound)

Posted by Im Rohit 45 6 years, 7 months ago

CBSE > Class 12 > Chemistry

1 answers

Gaurav Seth 6 years, 7 months ago

1) Optical Isomerism

Optical isomers are those two compounds with the same chemical formula such that their mirror images are not superimposable on each other. Depending on the direction they rotate the plane of polarised light in a polarimeter, we have two forms of optical isomers. They are:

Dextro Isomer: This rotates to right.
Laevo Isomer: This rotates to left.

2) Geometric Isomerism

In case of disubstituted complexes, the substituted groups could either be adjacent or opposite to each other. This leads to geometric isomerism. Thus, we can prepare square planar complexes such as [Pt(NH₃)₄Cl₂] in two forms, cis and trans. When the chlorine atoms are adjacent to each other, we get the cis form. While when two chlorine atoms are opposite, we get the trans-form.
