Reactants and products

– unscramble the bolded, capitalized letters. what words can you find? which word means start? which word means stop?

START and STOP, ReAcTanTS means START, PrOducTS means STOP

Explanation:

1. We find words 'STOP' and 'START'.

2. Let's take a look at the word 'ReAcTanTS'. Enumerate the capital letters from 1 to 5 from left to right, that is,

'1': R,

'2': A,

'3': T,

'4': T,

'5': S.

Notice that if we take a combination of 54213, we obtain a word 'start'. This has, of course, a chemical application. Reactants are the ones we start with in a chemical reaction.

3. Let's take a look at the word 'PrOducTS'. Enumerate the capital letters from 1 to 4 from left to right, that is:

'1': P,

'2': O,

'3': T,

'4': S.

Notice that if we take a combination of 4321, we obtain a word 'stop'. Similarly to the previous word, it also has a direct relationship to the chemical context. Products are formed in a chemical reaction when reactants combine. This is the point where reaction comes to and end and eventually stops if it's a typical one-sided reaction.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
