Part b one of these compounds is an anticancer drug, and one is inactive. the anticancer drug works by its chloride ions undergoing a substitution reaction with nitrogen atoms in dna that are close together, forming a n-pt-n angle of about 90°. which compound would you predict to be the anticancer drug? match the words in the left column to the appropriate blanks in the sentences on the right. reset cisplatin ci-pt-cl n-pt-n the atoms that will undergo substitution, in the compound angle, corresponding to the is about o, and the angle in the new dna complex needs to also be about 90 cl-pt-n transplatin 180 therefore, the cl atoms in occupy bonding sites that are in the correct orientation to bind adjacent n atoms in dna. the anticancer drug must be
