Question

The name of the compound is $bicyclo\left[ {2.2.1} \right]heptane$
If true enter 1, else enter 0.

Answer 1

Hint : To name this compound first label them according to the number of carbon present in the compound. This will make the naming of the structure simpler. Then follow the IUPAC rules for naming the cyclic compound.

Complete Step By Step Answer:
A bicyclic molecule is made up of two terms namely bi meaning two and cyclic meaning ring. Together they mean a molecule that features two joined rings. A bicyclic compound can be carboxylic, meaning all of the ring atoms are carbons, or heterocyclic, that is, the ring atom consists of at least two elements. Moreover two rings can be aliphatic or can be aromatic, or a combination of aliphatic and aromatic.
For a bicyclic compound three modes of ring junction are possible:
Spirocyclic compound- Two rings share only one single atoms
Fused or condensed bicyclic compounds- Two rings share two adjacent atoms
Bridged bicyclic compound- Two rings share three or more atoms, separating the two bridgehead atoms by a bridge containing at least one atom.
Now that we have understood what bicycle compounds are we will learn about their nomenclature.
The first step is to start the numbering from one of the bridgehead carbon atoms. The direction to number the bicyclic compound will be from the side having more carbon, then the second largest chain and so on. This decides the suffix or the root of the compound name.
If the ring is fused or bridged it gets the suffix bicycle, in case of spirocyclic we use suffix spiro.
In between these prefixes and suffixes a pair of brackets with number denotes the number of carbon atoms between each of bridgehead atoms which are arranged in descending order.
Let us look at the structure provided to us
The number of total carbons are seven and since it is a bicyclic compound therefore $bicycloheptane$
First two numbers represent the number of carbon atoms on the left and right side of the bridge which is two for each.
The last number is the number of carbon atoms in the bridge which is one.
Therefore the name of the compound is $bicyclo\left[ {2.2.1} \right]heptane$

Note :
To name such compounds one must be familiar with the root word for naming according to the number of carbon atoms present in the parent chain. Then see the direction at which the number of carbons to be counted. Finally putting the number in closed brackets according to the number of carbon between bridgehead carbon and in the bridge.
