If the dipole moment of AB molecule is given by 1.6 D and A - B the bond length is 1Å then % covalent character of the bond is

If the dipole moment of AB molecule is given by 1.2 D and A - B the bond length is 1­Å then % ionic character of the bond is [Given : 1 debye =10^(-18) esu. Cm]

If the dipole moment of AB molecules is given by 2.4 D and A-B the bond length is 1 Å than % covalent character of the bond is :

The vertices of a DeltaABC are A(3, 0), B (0, 6) and C (6, 9) . A straight line DE divides AB and AC in the ration 1:2 at D and E respectively, prove that (DeltaABC)/(DeltaADE) = 9

In a compound AB, electro negativity difference between A and B is 1.9. Atomic radius A and B are 4Å and 2Å . The distance between A and atoms means d_(A-B)

Two numbers A and B are such that the sum of 5% of A and 4% of B is two thirds of the sum of 6% of A and 8% of B. Find the ratio of A:B.2:3 b.1:1 c.3:4d.4:3

The vertices of a triangle ABC are A(3,0), B(0,6) and C(6,9) . A line DE divides both AB and AC in the ratio 1 : 2 meeting AB in D and AC in E . Prove that DeltaABC=9DeltaADE .

The equation of the line AB is y = x . If A and B lie on the same side of the line mirror 2x-y = 1 , then the equation of the image of AB is (a) x+y-2=0 (b) 8x+y-9=0 (c) 7x-y-6=0 (d) None of these
