Select the single best answer. Explain the observed trend in the melting points for four isomers of molecular formula C7H16. mp
damaskus [11]

Answer:

The ability of the molecule to pack more tightly increases the melting point.

Explanation:

In hydrocarbons of same molecular formula, melting point is determined by:

  • weak intermolecular forces
  • Molecular symmetry

Higher the intermolecular forces and molecular symmetry, higher will be the melting point.

Intermolecular forces in hydrocarbons decreases with branching. Moreover, branching interfere the tight packing of the molecule in the crystal. Therefore, branched hydrocarbons tend to have lower melting point.

However, in highly branched hydrocarbons molecular symmetry increases which results in tight packing of the molecule in the crystal.

So, highly tight packed molecules tend to have high melting point.

As (CH3)2CHC(CH3)3 is highly branched and has high molecular symmetry, therefore, its melting point is highest among given.

So, among the given, option c is correct.

5. In this lab, you continued to add Reagent D to each solution until it turned blue. The purpose was to remove the oxygen to me
Basile [38]
A solution is turning blue means, it is turning it's behavior to Basic from Acidic. Reagent D must be a Basic component so it is increasing the pH of the solution. As reaction does not depend on the phase of the component, it could be anything i.e., Solid, Liquid or gas.

Hope this helps!
