Thanku
Thank you so much

How will you carry out following conversionsof ethyne 1-butyne
In the 2 question ,in product there is a extra hydrogen attached to te c-atom
Super it easy to understand thanks
in (xix) its not tert butyl bromide real str. Dont be confuse guys i think they also have copied this ans from my cbse guide app there also it is wrong
apology for that yes there is one extra bromine in the structure ,it will be rePlaced by one methyl group but the structure arrangement will in the same format as shown in the answer
No man, the diagram shows 2,2-Dibromopropane but it should be 2-Bromo-2-methylpropane(tert-butyl bromide) Do you understand what I mean....... There are 2 br
No the structure is not wrong in the 19 th part , tertiary butyl bromide can be drawn in this form also
