O ne of the major problems in student life is to focus on the studies. This article is not only important for the students who are preparing for board exam but also important for those who are preparing for any competitive exam. If you follow the instructions carefully then you will see a major change in your study pattern, your focus ability and your concentration level. Making an Effective Time table The first problem that students face during their study routine is to make a timetable and follow it. Many students make timetable, work accordingly to it for some days or a couple of weeks but aren't able to follow the timetable for a long period of time. So what is the mistake here; the problem here is that most of the students' timetable is focused on the subjects that they have to study and not on the other activities that they also have to do in that time period like breakfast, lunch, dinner, bathing, relaxing and some other little things that they might have to do of which...
Co-ordinate bond is type of bond which is formed between two atoms in which one atom completely donates its two electron or one lone pair to second atom. What we usually see in covalent bond is that in covalent bond 1 electron is shared by one atom and the another electron is shared by II atom, so in covalent bond there is sharing of electrons. But in co-ordinate bond, the two electrons come from single atom which is called donor atom(as it donates its lone pair) and the atom to which lone pairs are donated , or we can say the atom which is receiving electrons or lone pair is known as receiver atom. Now the question arises that oxygen has 6 electrons and if it gets two more electrons, then its octet will be completed and it will become stable. During the formation of a co-ordinate bond the donor atom donates two electrons which suggests that the donor atom has two free electrons which are not involved with any other atom in bond i.e., they are just free to use. So why ...
