Preparations For Board Examinations

Dear Students ,

Till now most of you either met with your Pre board exams or are about to face them.

Don’t worry , but make your game plan to for these exams .

Try to understand following  –

(a)How much you Know about the subject?

(b)How much days are left for your exams?

(c)Do you really want success in these examinations or simply wish to have ?

If your answer is in favour of these exams than try to make your game plan by considering following –

(1)Try to take tips from your teachers regarding –

a. Minimum syllabus to get 70% marks.

b. Get evaluated  yourself from your teachers. (Never try to evaluate yourself by You , it can make you over confident or under confident)

c. Make a minimum content  based schedule for the preparations subject wise.

d. Try to prepare at least for 2 marks for  each subject daily.

e. Get enrolled yourself In a TEST SERIES to have continuous check  on your preparations.

Subject Enrichment

Some Vocabulary – Organic Chemistry

Achiral –lacking handedness – a molecules is achiral if it is superimposable on its mirror image.

Addition reaction – the reaction wheretwo reactants combine to form a single new product – typically the addition of a halogen, hydrogen, HCl to a double bond.

Aromatic – a class of compounds that contain a benzene-like six-membered ring with three apparent double bonds.

Carbocation – a carbon cation or a carbon which makes three covelent bonds and has only six valence electrons in outer energy level. Has a trigonal planar molecular geometry.

Chiral – Handed.  A molecule that is not superimposable on its mirror image.

Cis-trans isomers (geometric isomers) – stereoisomers (same connection of atoms) that differ in their arrangement in

space about a double bond or ring.

Dehydration reaction – elimination of water from an alcohol to form an alkene.

Electrophile – an electron-poor molecule or anion that can accept an electron pair from an electron-rich molecule or  cation.

Enantiomers – stereoisomers (same connection of atoms) whose mirror images are non-superimposable.

Functional  group – an atom or group of atoms that is part of a larger molecule and has a characteristic chemical  reactivity.

Mechanism – a complete step-by-step description of how a reaction happens.  The movement of a pair of electrons as the  reaction occurs, is represeted by the complete arrows.

Nylon – a polymer with many amide linkages prepared by the reaction between a diacid and a diamine.

Nucleophile – an electron-rich molecule or anion that can donate an electron pair to an electron-poor molecule or cation.

Nucleophilic substitution reaction – a substitution reaction in which one nucleophile replaces another.

Optical activity – the ability of a molecule in solution to rotate plane-polarized light.

Plane-polarized light – ordinary light that its electric vectors in a single plane rather than in random planes.

Polyester – a polymer with many ester linkages prepared by the reaction between a diacid and a dialcohol.

Racemic mixture – a 50:50 mixture of two enantiomers of a chiral substances – shows no optical activity.

Free Radical – a highly reactive neutral atom or molecule which has an odd number of electrons.

Resonance forms – representations of a molecule that differ only in where the bonding electrons are placed.

Stereochemistry – the branch of chemistry concerned with the three dimensional arrangement of atoms in molecules.

Structural isomers –molecules with the same molecular formula but whose atoms are connected by covalent bonds in a different order.

Students Problem


Students solutions means to work for students problems.

Common problem which a child/student face …

(a)Apathy towards study.

(b) Often getting confused while selecting a proper stream of academics that is suitable to

their intellectual capabilities.

(c) Frequently changing moods, therefore unable to concentrate the studies.

(e) Confused state of mind, which may delay decision making.

(f) Getting blank while attempting the exam papers and unable to recall it again.

(g)Habit of anticipating failure, even before starting work on the task.

(h) Escapism tendencies, often owing to non-interesting stream of academics; forcibly

imposed by the parents.

(i)Habit of finding excuses, so as to avoid studies on that pretext; also very slow in grasping.

(j) Fear of exams.

(j) Habit of finding excuses, so as to avoid studies on that pretext; also very slow in grasping.
