A Group VIIA atom combines with a Group IA atom. The bond formed between them will most likely be:
ad-work [718]

Answer: The correct answer is option B.

Explanation:

  • Ionic bond is formed when there is complete transfer of electrons from one element to another.
  • Covalent bond is formed by the sharing of electrons between two elements.
  • Metallic bond is formed when two metals combine together.

Electronic Configuration of Group VII-A : ns^2np^5

This group require 1 electron to attain stable electronic configuration.

Electronic configuration of Group I-A : ns^1

This group will loose 1 electron to attain stable electronic configuration.

So, there will be complete transfer of electron from Group VII-A to Group I-A and hence, will form ionic bond between them.

Hence, the correct option is B.

Rank the following alkenes in order of increasing stability of the double bond towards addition of HBr:
ASHA 777 [7]

Answer:

2,3-dimethyl-2-butene > 3-methyl-3-hexene > cis-3-hexene > 1-hexene

Explanation:

According to Saytzeff rule, the more highly substituted an alkene is, the more stable it is. Since this is so, 2,3-dimethyl-2-butene will be the most stable of all the alkenes listed because it is the most substituted alkene.

Let us also note that terminal alkenes are the least stable because the pi bonds of the alkenes are least stabilized by alkyl groups. This implies that 1-hexene is the least stable alkene among the listed alkenes.
