Answer:

D. The mass ratio of oxygen to carbon in CO is twice the mass ratio of oxygen to carbon in CO2

Explanation:

Mass of Oxygen in 1 mole of substance = 16g

Mass of carbon in 1 mole of the same substance = 12g

Ratio of O : C = 12/16

= 1 : 0.75

Mass of oxygen in O2 = (16*2) = 32 g

Mass of carbon = 12 g

Mass ratio of O2 : C

= 32 : 12

= 12/32

= 1 : 0.375

From the calculations above, The mass ratio of oxygen to carbon in CO is twice the mass ratio of oxygen to carbon in CO2.

Answer:

2-methyl-2-pentanol is produced as a major product

Explanation:

Double bond in 2-methyl-2-pentene is protonated first by consuming a proton from $H_{2}SO_{4}$ .
A carbocation intermediate is formed after protonation of double bond. Most stable carbocation is formed as a major intermediate.
Here a tertiary carbocation is formed as a major intermediate.
$H_{2}O$ gives subsequent nucleophilic addition to the carbocation intermediate and produce 2-methyl-2-pentanol as a major product.
Reaction mechanism and major organic product has been shown below.
