Oceans, they are larger than ponds hence they possess wider exposure with more number of surface molecules.
Correct answer: <span>An isomer with a branched structure will require:
less energy to melt than the straight chain structure.
Reason:
</span>
The branched chain compounds have lower melting and boiling points as compared to straight chain isomers.This is due to the fact that branching makes the molecule more compact. This results in decreases in surface area of isomer. But, the intermolecular attractive forces depends on the surface area of compound. Thus, branched isomers have lower intermolecular force of interaction, as compared to straight chain isomers. Consequently, the melting/boiling points of the branched chain isomers are lower as compared to straight chain isomers.
I think the correct answer from the choices listed above is option C. It would be octane that is an organic compound. <span>They are, any of a large class of chemical compounds in which one or more atoms of </span>carbon <span>are covalently linked to atoms of other elements, most commonly </span>hydrogen<span>, </span>oxygen<span>, or </span>nitrogen<span>.</span>
