Which of the following molecules does not have a geometric isomer? Which of the following molecules does not have a geometric isomer? MX3Y3 (octahedral shape). A central metal atom is bonded left into and out of the page and right into the page to X, and above, below, and right out of the page to Y. MX4Y2 (octahedral shape). A central metal atom is bonded right into and out of the page and left into and out of the page to four Xs, and above and below to Y. MX3Y (tetrahedral shape). A central metal atom is single bonded to three Xs above and right into and out of the page, and left to Y. MX2Y2 (square planar shape). A central metal atom is single bonded right to two Ys and left to two Xs.

i can ! i just need to know what the paragraph is! : p

a. they are both space stations

happy to

pls mark as brainliest.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
