Free rotation is possible with respect to a C-C bond in the case of alkanes. c) An alkene on ozonolysis followed by reduction of the ozonide formed with zinc and water gave a mixture of ethanal and methanal. ii) Illustrate the above mentioned the above mentioned reaction using the chemical equation.

A spacial arrangements of atoms which can be converted into one another by rotation arround a C-C single bond are called conformations. i) Represent Sawhorse and Newman projection formulae of staggered and eclipsed conformation of ethane.

a, What are inter-halogen compounds? Give any two example. b. The number of electrons 'in the valence shell decides the oxidation state of an element What are the possible oxidation states of Pb? Atomic number of 'Pb=82' Which is more stable? Why?

Controlled oxidation of alkanes in the presence of suitable catalysts give a variety of products. Free rotation about a carbon - carbon single bond is permitted in an alkane molecule. What are conformers? Draw the structure of the eclipsed and staggered conformers of ethane in Sawhorse and Newman projection and explain their relative stability.

Conformations are those special arrangements which are obtained by rotation around sigma bonds. Draw the staggered and eclipsed conformation of ethane.

The symbols of some metals are given below. Pb, Fe, Sn, Na, Au a) Which metal is produced by using electricity as reducing agent? b) Which metal exist in the free state? c) Which compounds of these metals are more stable?

The relative velocity of a body A with respect to a body B is the time rate at which body A changes its position with respect to body B . a)If V_A and V_B are the velocities of A and B moving in opposite directions,what is the relative velocity of A with respect to B ? b)Two trains along the same straight rails are moving with constant velocity of 60km/h and 30km/h towards each other.If at time t=0 ,the distance between them is 90km ,find the time when they collide. c)The velocity time graph of two bodies A and B make angles of 30° and 60° with the time axis,what is the ratio of their acceleration?
