Explanation:
Carbon dioxide isn't a polar molecule because
same nature of charge appears in opposite direction which cancel each other. So, carbon dioxide is non-polar molecule.
Structure of a-chloro-b-methylbutyric acid (2-chloro-3-methylbutyric acid is attached below.
The structure was drawn using following information.
1) First, the parent chain was identified. The parent chain is containing four carbon atoms, also, this chain belongs to carboxylic acid as the compound name ends with Butyric acid i.e. butyr (Butane) -ic acid (carboxylic acid).
2) Secondly, the positions of substituents were assigned by using the rule which sates that the numbering in carboxylic acid must satrt from the carbonyl carbon. Therefore, the carbon which is attached to carbonyl carbon is named as alpha (2nd position) and carbon next to alpha carbon is named as beta carbon (3rd position). Hence, we add chlorine atom on 2nd carbon next to carbonyl group and methyl group at 3rd carbon with respect to carbonyl carbon.
Answer:
Node
Explanation:
Other examples of nodes include servers, personal computers, hubs switches, modems, and etcetera. These devices must be connected together in a network such as an Ethernet or WiFi. These nodes are given addresses depending on the communications layer they operate on the network.
