First choice: PhH4 has a lower boiling point
Second: SiF4 higher
Third: CBr4 higher
<span>A covalent bond is a bond formed by atom sharing.
In water molecule, there are twice the number of hydrogen atoms than the oxygen atoms. Its structure is H-O-H. The electronegative difference between the H and O allows them to be polar because on side there is positive charge and on another side there is negative charge.</span>
Flammability
Hope it helps!
I believe the answer would be Neutrons
