7:30 p.m. on (9) (14) Young Sheldon.
This prequel to “The Big Bang Theory” closes its fourth season with a finale called “The Wild and Woolly World of Nonlinear Dynamics,” in which young Missy’s (Raegan Revord) first heartbreak sparks a series of events affecting brother Sheldon (Iain Armitage) and the entire Cooper household. Fans can rest easy on one point, though: There’s no real-world heartache for this show’s cast and creative team, since CBS recently renewed “Young Sheldon” for three more seasons.
9 p.m. on (15) Last Man Standing.
After Mike (Tim Allen) spends time with Ryan (Jordan Masterson) during a marketing retreat, Mandy (Molly

9:01 p.m. on (13) (14) Mom.
This Emmy-winning comedy series, which received widespread acclaim for skillfully juggling laughter and pathos, ends its eight season run with a finale called “My Kinda People and the Big To-Do,” in which Bonnie (Allison Janney) gains a new perspective on her sobriety when she is forced to deal with some difficult news. In a happier development, Jill and Andy (Jaime
Pressly, recurring guest star Will Sasso) take a major step in their own relationship. Mimi Kennedy, William Fichtner, Kristen Johnston and Beth Hall also star
9:30 p.m. on (14) B Positive.
After long weeks of babysitting Gina (Annaleigh Ashford) — and, more to the point, the kidney she’s willing to donate to him — Drew (Thomas Middleditch) understandably feels immense relief as his transplant surgery nears in the Season 1 finale, “Life Expectancy.” While he celebrates what he fervently hopes is his last dialysis session, Gina starts searching for an apartment she can move into after the operation. Linda Lavin and Sara Rue also star. CBS has not yet announced whether this show will return for another season.
10:01 p.m. on (9) (16) Rebel.
After Helen (guest star Mary McDonnell) is denied critical surgery, Rebel (Katey Sagal) goes to the mat to save her life, and continues to push Cruz (Andy Garcia) to recall the heart valve for closer study in the new episode “Heart Burned.” Elsewhere, Cassidy and Lana (Lex Scott Davis, Tamala Reneé Jones) try to help Luke (Sam Palladio) when his personal life threatens both his career and personal reputation. Mo McRae, Adam Arkin, Abigail Spencer, Dan Bucatinsky and Sharon Lawrence guest star.
