For Carbocation the Stability Order Will be _________________.

Detailed Solution: Question 7

Rules for Naming Hydrocarbons:-

Rule-I Selection of the longest carbon chain.

Rule-ll Numbering the longest chain: Longest chain is numbered starting from a terminal carbon. Numbering is done in such a way that the lowest possible number is given to the sidechain or a functional group.

Rule-Ill Writing names of branched, saturated hydrocarbons, locants are written first in alphabetical order followed by the name of the parent chain.

Rule-IV Some common names are retained in IUP AC system for unsubstituted hydrocarbons only. Stability order: D > C > B > A

Electron withdrawing groups destabilize carbocation. Here, Cl is an electron-withdrawing group hence, it destabilizes the carbonation. But as the distance increases between carbocation and electron-withdrawing groups which can be seen in A, B, and C molecules. Hence, an order is C > B > A and in the case of (D) molecules, there is no electron-withdrawing group. Hence, it's more stable as compared to others.

*Multiple options can be correct

Graphite differs from diamond because graphite is:

This question has multiple correct options

Detailed Solution: Question 8

Graphite differs from diamond because graphite is slippery to touch and a good conductor of electricity. In graphite, free electrons move throughout the entire layers, and hence graphite is a good conductor of electricity. Whereas in diamond, there are no mobile electrons in the system. Hence, diamond crystals are non-conductor of electricity. Diamond is a hard beautiful crystalline substance.

The IUPAC name of the compound CH3CH = CHC = CH is:

Detailed Solution: Question 9

According to the rules of IUPAC,

In an organic compound having multiples bonds the order of preference is given as,

Triple bond>Double bond>Single bond So,

We should number the carbon from the right. As it can be seen from the figure the correct order of numbering and nomenclature is right one. The left part violated the IUPAC rule stated above and hence the correct IUPAC name of the compound will be pent-3-en-1-yne.

The process of making soap by the hydrolysis of fats and oils with alkalis is called:

Detailed Solution: Question 11

Saponification is a process when triglyceride is treated with strong base,lye which accelerates the cleavage of ester bond and releases fatty acids and glycerol. Soaps are precipitated by salting it out with saturated sodium chloride.
