• In the field of polymer chemistry, which statement accurately describes the concept of 'tacticity' and its impact on the physical properties of polymers?

  A) Tacticity in polymers refers to the length of the polymer chain, and higher tacticity correlates with increased tensile strength and melting point.

  B) It describes the regularity in the configuration of chiral centers along the polymer chain; isotactic polymers, with identical configuration at each chiral center, generally have lower melting points and are less crystalline compared to atactic polymers.

  C) Tacticity pertains to the arrangement of substituent groups relative to the polymer backbone; isotactic polymers, with a uniform arrangement, often exhibit higher crystallinity and melting points than their atactic or syndiotactic counterparts.

  D) The term 'tacticity' is used to describe the branching density in polymers, with higher tacticity indicating more branching and resulting in polymers that are more rigid and brittle.
