Answer:because it isnt flammable
Explanation:water can not be burned
We can express the rate equation in this form:
-r = k A^n B^m
where -r is the rate
k is the rate constant,
A is the concentration of CH3Cl
n is the order with respect to CH3Cl
B is the concentration of H2O
m is the order with respect to H2O
We can solve this by trial and error or by calculus. The first method is easier. The rate constant does not depend on the concentration of the reactant. Assume values of n and m and solve for k in each experiment. The only option that gives really close values of k in each experiment is:

Answer : The correct option is, electrons are not shared equally between atoms.
Explanation :
Polar covalent bond : It is a type of chemical bond in which a pair of electrons are not shared equally between the two atoms.
In polar covalent bond, the electrons are not shared equally because one atom spends more time with the electrons than the another atom. In this, one atom has more tendency to pull an electron than the other atom.
For example : 
is an example of polar covalent bond. In water molecule, oxygen spends more time with the electron than the hydrogen and oxygen carries a partial negative charge.
Water is solvent, salt is solute, reactants are H2O and NaCl, and the whole thing is solution
