Answer:
2,3 -Dimethyl pentane
Explanation:
The given molecule is 2,3-Dimethyl pentane.
First of all select the longest chain of C-C atom. This will be the parent name.
In given structure the longest chain is straight chain that contain five carbon. Thus the parent name will pentane and there is no double or triple bond the given structure is of alkane.
Than locate the positions of functional groups attached.
In given structure there are two methyl groups are present. Give the name in such a way that functional groups will have lowest number. In given case we will start from the left.
The first methyl group will have number 2 and second will have number 3.
The name will be,
2,3-Dimethyl pentane
Answer:

Answer:
Molecular compound and ionic compound
Explanation:
Molecular compounds include a prefix on the first and second elements and a suffix on the second element, whereas Ionic compounds do not have prefixes and only include a suffix on the second element.
Answer:
A. Non-metal
B. Six
C. 2
D.NA2O
E.Oxygen
Explanation:
Oxygen is the element in the second period (second horizontal row) and Group VI A of the periodic table. These properties apply to oxygen
Answer:
C. Scientists accepted the model at first but later rejected it.
Explanation:
Scientists accepted the model at first because it explained the hydrogen emission spectrum.
However, with the development of quantum mechanics, scientists had to modify the model (not reject it).
Electrons still had specific energies, but they no longer travelled in fixed orbits.
Instead, electrons had a probability of being found in a given region of space.
