This 9th class chemistry chapter 3 online test covers Chapter 3 of the Class 9 Chemistry course, Chemical Bonding. It has 25 multiple-choice questions, shown one at a time, and it marks itself the moment you finish. There is no timer and no sign-up. When you press finish you get your score, and every question is shown again with your answer, the correct option and a short explanation of why that option is right. An Urdu medium version of the same test is further down this page.
What the 25 Questions Test
The questions are spread across the whole of Chapter 3 rather than one section, and most of them ask you to apply something rather than simply recall it. Expect to be doing the following:
- Deciding whether a given compound is held together by ionic or covalent bonding.
- Counting shared pairs in a single, double or triple bond.
- Recognising a coordinate covalent bond from the way the electrons were supplied.
- Predicting whether a compound conducts electricity, and in which state.
- Matching a property such as melting point to the bonding type that causes it.
- Identifying hydrogen bonding from a described situation.
Quick Recall Before You Start
These are the points Chemical Bonding questions turn on most often. Read them once, then begin:
- Transfer of electrons gives an ionic bond; sharing gives a covalent one.
- Both electrons in a coordinate bond come from the same atom.
- Ionic compounds conduct when molten or dissolved, never as a dry solid.
- Triple bonds share three pairs, double bonds two, single bonds one.
Traps Hidden in the Wrong Options
In a well-built multiple-choice test the wrong answers are not random; each one is placed there because students genuinely believe it. In this chapter look out for:
- An option describing ionic bonding as sharing.
- A claim that solid ionic compounds conduct.
- Counting the wrong number of shared pairs in a multiple bond.
How the Test Works
- 25 questions, one at a time, with Next and Previous buttons.
- No timer, so you can work a calculation out on paper first.
- Automatic marking as soon as you finish.
- Answer review showing the correct option and an explanation for every question.
- Retake as often as you like; your score is not stored anywhere.
Start the Chapter 3 Online Test
In Chapter 3 the decisive words are usually “transfer” and “share”, so find them in the question before you look at the options. Read each question to the end before looking at the options, because one word such as “only”, “always” or “molten” can decide which answer is correct. Aim for 20 out of 25 or better before moving on.
Chapter 3 Online Test — Urdu Medium
Urdu medium students can attempt the same Chapter 3 test with every question, option and explanation written in Urdu. It behaves exactly like the English test above: 25 questions one at a time, no timer, and a full answer review at the end.
What to Do With Your Score
The score matters less than the review that follows it. Note the topic behind each wrong answer rather than the question number, and if several come from one part of the chapter, revise that part alone. For Chapter 3 the part worth securing first is bonding types, which decide the physical properties asked about later in the course. Retake the test a day or two later rather than straight away, then move to the written paper, where you have to produce the answer instead of recognising it.
Frequently Asked Questions
How can I tell whether a compound is ionic or covalent?
Look at what the atoms did with the electrons. Complete transfer, usually between a metal and a non-metal, gives an ionic bond. Sharing, usually between two non-metals, gives a covalent one.
Why does an ionic solid not conduct electricity?
Because the ions are locked in place in the lattice. Conduction needs charged particles free to move, which only happens once the solid is melted or dissolved.
Is this test free?
Yes. There is no sign-up, no limit on retakes and nothing is locked. Your score is not saved or shared.
