Q:

What types of orbital overlap occur in Cumulene?

Answer

A cumulene is a hydrocarbon with three or more cumulative double bonds. They are analogous to allenes, only having a more extensive chain. The simplest molecule in this class is butatriene, which is also called simply cumulene.


 


The carbons on the ends are sp² hybridized, with a p-orbital for the 'second' bond in the double bond with their neighboring carbons.


They have those sp² orbitals overlapping with the s from the hydrogen, and they have a p overlapping in the pi bond with the neighboring carbon. They also have a sigma bond with the neighboring carbon I'll get to.


The middle carbons each have two pi bonds with their neighbors, leaving sp hybridiaztion for the rest. So they have sp/sp² with the end carbons, and sp/sp with each other. (And they also have p/p in the pi bonds).


 


All orbital overlappings in Cumuene are :


* s/sp²


* p/p


* sp/sp²


* sp/sp

Q:

Which sociological perspective is most closely linked to microsociology?

A) symbolic interactionism B) the feminist perspective
C) structural functionalism D) the conflict perspective
 
Answer & Explanation Answer: A) symbolic interactionism

Explanation:

There are two types of sociological theories:

1. Macro and

2. Micro.

Macro theories focus on the society as a whole and aim at establishing the general characteristics of the society. It is basically looking at the society as a whole and looking at a bigger picture. It aims to answer three basic questions:

1) What holds the societies together?

2) What are the sources of conflict in a society?

3) How do societies change?

There are two branches of macro-sociological theories: consensus and conflict, with the main representative being functionalist and marxist respectively.

 

Micro theories on the other hand, focus on the individuals who make up the society unlike macro theory which looks at the society as a whole. Micro theories are small scale. Consider it a magnifying glass, when you look through it, you 'zoom' in to the society and see the individuals who have made up that particular society.

 

Symbolic interactionism is the sociological perspective which is most closely linked to microsociology.
