The Maharashtra State Board of Secondary and Higher Secondary Education (Abbreviation: MSBSHSE) is a statutory and autonomous body established under the "Maharashtra Secondary Boards Act" 1965 (amended in 1977). [1] Most important task of the board, among few others, is to conduct the SSC for 10th class and HSC for 12th class examinations. [2]
Apart from this all NCERT books are available in Flip book format. NROER is an collaborative platform, intend to reached the un-reached [ 2 ] and institutions like SCERT , SIERT, SIE, Vigyan Prasar , CCERT, Gujarat Institute of Educational Technology (GIET), SIET and other stake holders have their share in the educational content.
Textbooks published by NCERT are prescribed by the Central Board of Secondary Education (CBSE) [8] from classes I to XII, with exceptions for a few subjects, especially for the Class 10 and 12 Board Examination. Around 19 school boards from 14 states have adopted or adapted the books. [11]
Unsaturated compounds generally carry out typical addition reactions that are not possible with saturated compounds such as alkanes. A saturated organic compound has only single bonds between carbon atoms. An important class of saturated compounds are the alkanes. Many saturated compounds have functional groups, e.g., alcohols.
In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [1] Alkanes have the general chemical formula C n H 2n+2.
Higher alkanes are naturally present in crude oil and can be obtained via fractional distillation.Saturated fatty acids decarboxylate to higher alkanes. Long olefins can be hydrogenated to yield higher alkanes. n-alkanes can be isolated via the formation of urea clathrates.They can also be synthesized through Kolbe electrolysis or other coupling reactions like the Wurtz reaction.
The naming of polycyclic alkanes such as bicyclic alkanes and spiro alkanes is more complex, with the base name indicating the number of carbons in the ring system, a prefix indicating the number of rings ( "bicyclo-" or "spiro-"), and a numeric prefix before that indicating the number of carbons in each part of each ring, exclusive of ...
