To help you answer this question, you can search a sample reaction in the internet for hydroboration-oxidation. Take a look at the attached picture. The sample reaction is shown at the top. We can deduce that the original compound must be an alkene. Following the pattern, compound a must be 2-methylbutene as shown in the picture.
The density of water at 12°C is lower than the density of water at 20°C.
Now density is related to volume as per: density = mass / volume =>
mass = volume * density.
So, the greaer the density the higher the mass of the same volume of water.
Therefore, 100.0 ml of water at 12°C has a mass greater than 100.00 ml of water at 20 °C.
