The most stable conformation of cyclopentane is the envelope.
It should be in such a conformation that the ethyl group is at the e-bond position or, in other words, a more horizontal position.
The chair conformation (all-staggered) is the most stable one.
Please see discussion!!
Yes, the chair confirmation of cyclohexane is more stable than the boat confirmation. The decreased stability of the of the boat conformation is caused by the nonbonding interactions generated by the close proximity of the 2 hydrogen atoms on c1 and c4 and by the eclipsing of hydrogens along the c2-c3 and c5-c6 bonds.

Cyclohexane is flammable.
Cyclohexane has no charge. It is a compound, not an ion.
Cyclohexane (C6H12) is a cycloalkane, not an esther.

chair form as the steric repulsions is minimum

No: cyclohexane can exist in a few different conformations, none of which are planar. The most stable conformation is one that looks like a chair.Other conformations include the boat and (more rarely - usually only as an intermediate) twisted boat conformations.The reason why cyclohexane in not flat is because its ring carbons are sp3 hybridised and hence they are at their lowest energy when the angle between substituents in 109.5°. In a perfectly flat hexagon the C-C angles would be 120°, thus incurring a hypothetical 11° of ring strain.Therefore, by "puckering" into the chair conformation, cyclohexane attains the structure of lowest potential energy.
No, sodium chloride is not soluble in cyclohexane.

No, cyclohexane is a neutral compound.
water is polar and the cyclohexane is not
