Overviews and facts-The hypothesis of the experiment was correct. Keep the readings in the ammeter constant throughout the above observation. Write the structures of its monomers and the repeating unit.
No : Examiner Teacher-in charge. Distinction Between Crystalline and Amorphous Solids S. Actinoids - Electronic configuration, oxidation states and comparison with lanthanoids.
From medical applications to gene studies, having a foundation knowledge of Chemistry better equips students to theorize concepts and bring applications to life. The constituent particles atoms, molecules or ions are closely packed and held together by strong interparticle forces Types of Solids The solids are of two types : Crystalline solids and amorphous solids. Remove the key K and allow the wire to cool, if heated. We only can provide stuff like sample paper, blueprint or other important information to you but hard work is yours you have to do hard work to get place in the merit list. Phenols: Nomenclature, methods of preparation, physical and chemical properties, acidic nature of phenol, electrophillic substitution reactions, uses of phenols. The conductivity is due to the presence of negative charge electrons , ii p·type semiconductors Silicon doped with 13 group element like gallium is called p-type semiconductor. Take five sets of observations. At the same time, you must have the basic knowledge of all the chapters. Give the structural formula of a and write the equations for all the reactions. Next, introduce some resistance R in the circuit from the resistance box.
CBSE Revision Notes for class 12 Chemistry - It consist all types of questions with a well explain Solution in a well organised manner.
Butyl-3-iodoheptane iv 1,4-Dibromobut-2-ene v 1-Bromo-4-sec. Write structures of different dihalogen derivatives of propane. Among the isomeric alkanes of mdlecular formula C 5H 12, identify the one that on photochemical chlorination yields i A single monochloride. In S N1 reactions, the reactivity depends upon chemistry class 12 stability of carbocations. The p-isomer being more symmetrical fits closely in the crystal lattice and thus has stronger inter- molecular forces of attraction than o- and m-isomers. Since during melting or dissolution, the crystal lattice breaks, therefore, a large amount of energy is needed to melt or dissolve the p-isomer than the corresponding o-and m-isomers. In other words, the melting point of the p-isomer is higher and its solubility lower than the corresponding o-and m-isomers. When a is reacted with sodium metal it give compound dC 8H 18 which is different from the compound formed when n-butyl bromide is reacted with sodium. Give the structural formula of a and write the equations for all the reactions. Therefore, compound c is tert-butyl bromide which is an isomer of compound a ,i. Thus a is isobutyl bromide, b is 2-methyl-1 -propane, c is tert-butylbromide, and d is 2,5-dimethylhexane.
