c. tetrahedral

d. linear

Answer 1

order of priority of functional groups

carboxylic acid > carboxylic acid derivatives > aldehyde > nitriles> ketones > alcohol> ehters> amine> alkene> alkyne> alkyl> substituents

-F<CH3<CH2F<-COOH

c. –F, –CH3, –CH2F, –COOH   >>>answer

In saturated hydrocarbons carbon involve in Sp^3 hybridization . The geometry is tetrahydral

c. tetrahedral >>>>answer
