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
<span>Endothermic reactions take in heat from the environment in order to react while exothermic reactions release heat during the reaction. For this, D must be true as the products have less energy because they have released heat during the reaction. A and C are incorrect because they products and reactants are equal and B is wrong because the energy of the products would be more as the reaction took in heat.</span>
First you find the molar mass of the formula.
3C: 36.03g + 8H:8.08g + N: 14.01g + 5O: 80g + P: 30.97g = 169.09g
Then do the mole ratio (304.3g)x(1mole/169.09g) = 1.800 moles
