- Also, previous arrays made in a similar manner suffer from steric effects that tend to favor certain R groups, so there may not be equal amounts of all 4 billion compounds, maybe more like a few million, which is still a lot. But when we looked at smaller arrays, each step had some chemicals that reacted well and some that did not work well, so not all steps worked well, much like peptide synthesis.

Morphology
steric = stereochemistry (opaque) = stere + ic
Formed from the combining form 'stere-' (not a common standalone English word) plus the adjectival suffix '-ic'; the combining form is technical and not obvious to average learners.
Etymology
Steric comes from the Greek root stereos, meaning 'solid' or 'three-dimensional', and you can see the same root in the word stereo. Think of a solid object that takes up space and gets in the way, so steric describes how the shape and space of parts of a molecule can block or change chemical reactions.
