The answer is (d.) They contain only single bonds.
The hydrocarbons which only contain single bonds between the carbon atoms are referred as saturated hydrocarbons. These hydrocarbons have carbon atoms bonded by many hydrogen atoms making it saturated. These are also the simplest class of hydrocardons.
The rate of a reaction refers to the speed at which the reaction takes place. The rate of a reaction depends on many variables such as, temperature, concentration of dissolved reactants, pressure of gaseous reactants, surface area of solid reactants, or the presence of a catalyst. In order to measure the rate of a reaction, we must measure the change in amount of a reactant as it is consumed over time, or measure the amount of product formed over time. When you graph the formation of a product, or consumption of a reactant on the y axis, versus the time of reaction on the x-axis, the slope of this function will provide the rate of the reaction.
Mass number is the sum of protons and neutrons.
Atomic number is the total number of protons present.
Mass number = protons + neutrons
Atomic number = protons present.
From the above equations we can conclude that,
Atomic number= Mass number- neutrons.
Thus we can find out the atomic number by subtracting the number of neutrons from the mass number.
