SnCL2 is solid while SnCl4 is liquid ...?

1 answer:

5 0

SnCl2 is solid at room temperature. Its melting point is 247 °C.

SnCl4 is liquid at room temperature. Is melting point is - 33°C.

The reason of this is every molecule of SnCl2 has a pair of non shared electrons which form a chloride bridge with neighbors molecules (the highly electronegative Cl attracts the pair of non shared electrons of the SnCl2 molecule), so they form a crystalline network.

zaharov [31]

If he was 30.8% too low, it means that he was at 69.2% of the boiling point needed. So 50o C is 69.2% of total.

In order to know what 100% is, you can divide the number by it's percentage and then multiply it by a hundred.

So: 50/30.8=1.623
1.623*100=162.3
So the correct boiling point of the liquid he was working with in the lab is 162.3 oC
