Draw the bond-line (not Lewis) structure for all the constitutionally isomeric compounds having the given molecular formula.

See explanation and image attached

Explanation:

The formula here is C4H10.

When we talk about constitutional isomers, constitutional isomers are compounds having the same molecular formula but different atom-to-atom connectivity.

The two main constitutional isomers of the formula C4H10 are butane and 2-methylpropane (iso-butane). The both structures are shown in the image attached.

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml
