1-Bromo-4-sec. butyl-2-methyl benzene is :-

(a) 1-chloropropane
(b) iso-propyl chloride
(c) 1-chlorobutane
Correct order of boiling point is -

Statement-I: The reaction of phenol with acid chloride is carried out in presence of a base (pyridine) so as to neutralise HCl, which is formed during the reaction.
Statement-II: Aspirin can be formed by the acetylation of salicylic acid.

Select the correct option:

Which of the following has lowest Pk_a value?

An organic compound C₃H₆O forms an orange red precipitate with 2,4-D.N.P. but it does not give tollen's test compound is :-

Glucose and Galactose are :-

The sodium fusion extract is boiled with iron (II) sulphate and then acidified with concentrated sulphuric acid. The formation of Prussian blue colour confirm the presence of :-

Condition which is not required for aromaticity?

Assertion: The atomic size generally decreases across a period.
Reason: It is because within the period, the outer electrons are in the same valence shell and the effective nuclear charge increases as the atomic number increases resulting in the increased attraction of electrons to the nucleus.

Which of the following is not correct order for dipole moment?

Which of the following will exhibit only +3 oxidation state?

When dil. H₂SO₄ is added to aqueous solution of potassium chromate, yellow colour of solution turns to orange colour. It indicates:

Assertion (A) : From the value of |Ψ|² at different points within an atom, it is possible to predict the region around the nucleus where electron will most probably be found.
Reason (R) : With the help of quantum mechanical model of atom, exact position of an electron in an atom can be determined.

Consider following equilibrium :

Which of the following statement are correct :
(A) At low temperature, intensity of brown colour decreases.
(B) The equilibrium constant for given reaction increases as the temperature increases.
(C) At low temperature, the brown colour intensifies.
(D) On increasing pressure, the reaction goes in the forward direction.
