What are the relative stabilities of different conformations of ethane. Is it possible to isolate these at room temperature?

Why eclipsed and staggered forms of ethane cannot be isolated at room temperature?

Draw Sawhorse and Newman's projections of the different conformers of ethane.

What will be the product obtained diazotisation of aniline is carried out at room temperature?

Is it possible to isolate pure staggered ethane or, pure eclipsed ethane at room temperature? Explain?

Innumerable number of galvanic cells can be constructed on the pattern of Daneill cell by taking combination of different half cells. What is the potential of the above half cell at all temperatures?

S_N^1 reaction takes placed in two steps. The relative reactivity of an alkyl halide in S_N^1 reaction depends on the relative stability of carbocations formed by ionisation. What will happen to the optical activity of a dextro rotatory isomer of alkyl halide if it undergoes hydrolysis by S_N^1 mechanism ?

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.

Dihydrogen is relatively inert at room temperature . Give reason.

A heating element using nichrome connected to a 230V supply draws an initial current of 3.2A which settles after a few seconds to a steady value of 2.8A. What is the steady temperature of the heating element if the room temperature is 27.0^(o)C ? Temperature coefficient of resistance of nichrome averaged over the temperature range involved is 1.70 x 10^(-4) ^(0)C^(-1)
