Here in the Fischer's projection formula H atoms linked with both #C_2 andC_3# chiral carbon atoms are kept in horizontal lines and following CIP rule on both #C_2 andC_3# chiral carbon atoms the rotations in going along descending order of priority excluding H atom of least priority are in anticlockwise direction . So both #C_2 and C_3# chiral carbon atoms will be marked as R.

For #C_2 "The order" ->-OH>C_2H_5(CH_3)CH-.>CH_3-#

For #C_3 "The order" ->CH_3CHOH-.>C_2H_5-.>CH_3-#
