Read your questions please!!!

It has come to my attention that the latest common test was considered difficult.

Firstly, yes, it is to a certain level of difficulty, but with the basic knowledge, you should be able to infer the answers.

One question which was actually used in last year's prelim and sec 3 EOY paper, was given today.

Although titanium is a metal and chlorine is a non metal, but the statement says that the structure is simple covalent, SO YOU MUST FOLLOW WHAT THEY WRITE!!!

So anyone who is not flexible and draw ionic, too bad, you got the wrong answer.

For your information, titanium chloride is a special group of compound called organometallic compounds and it is covalent.

What is studied in secondary school is simplified and in every rule, there will be exceptions. So please read questions next time, students! :)
