There are two major reasons for this:- The interelectronic repulsions are the major reason for this phenomenon. The inner electrons repell upcoming electrons due to high electron density. The size of oxygen is small due to this the atom becomes less stable on addition of 2nd electron.
Stereoisomers:- these are the compounds that have same molecular formula but different arrangement of atoms in the space. Optical isomers:- the compunds that have same molecular formula but they rotate the plane polarised light to the different side, right side-dextrorotatory and left levorotatory. Enantiomer:- these are the compounds that are mirror images of each other and if they are present […]
Step 1: write the configuration of element and then show the valence elactrons around the symbol of element . Step2: make the bonds around the atom according to its valency […]
There are two reasons for less reactivity of Alkynes towards electrophillic addition reactions:- Due to greater electronegativity of sp-hybridized carbon atoms of a triple bond than sp2 -hybridized carbon atoms of a double bond, pie-electrons of alkynes are more tightly held by the carbon atoms than pie electrons of alkenes and hence are less easily available for reaction with electrophiles.
