1,4 - dibromobutane ( ie. a dibromoderivative of an alkane , butane) when reacted withl in ethereal solution produces alicyclic hydrocarbon, Cyclobutane as per following reaction.
Therefore , the dibromo-derivative of alkane is identified as 1 , 4-dibromobutane.
Ozonolysis of alkenes involves the addition of ozone molecule to alkene to form an unstable ozonide , and then cleavage of the ozonide by to smaller molecules .
2- butene is a symmetrical alkene , which on ozonolysis yields two moles of having molecular mass of 44 u. as per reaction given below,
In the following sequence of reactions, the alkene is converted to compound
The compound is --------- ?
The given sequence of conversion steps represent Ozonolysis of 2-Butene , which follows the following path ,
1 . Formation of an unstable intermediate / ozonide
2 . Cleavage of the intermediate / ozonide by to smaller molecules , giving out the compound , which is CH3 CHO ( Ethanal )
The reaction is well depicted as below ,
