Answer:
The molecule has two chiral carbons
Explanation:
i hope its the right answer
Explanation:
I think
Bonding pairs = 4
Lone pairs around the left chlorine atom = 9
The answer is b) Water.
a) and c) options are elements and d) option is a mixture.
At STP one mole of gas takes up 22.4L which means that the answer is B since there is 6.02×10²³ molecules in one mole of a substance.
I hope this helps. Let me know if anything is unclear.
Answer:
Here's what I get
Explanation:
1. Water
The O-H bond in water is highly polar.
It has about one-third ionic character.
The partially-positive H atoms and partially negative O atoms strongly attract each other by hydrogen bonds.
It takes a large amount of energy to separate the water molecules from each other.
Thus, the boiling point of water is relatively high (100 °C).
2. Acetone
The C=O bond in acetone is much less polar.
It is less than 20 % ionic.
The dipole-dipole attractions in acetone are much weaker than the hydrogen bonds in water.
It takes much less energy to separate the acetone molecules from each other.
Thus, even though the molar mass of acetone is more than three times that of water, the boiling point of acetone is only 56 °C.
