TPGS-750 M conducts reaction under lower temperature then the reactions carried out in organic solvents.
<h3>What is tpgs-750m ?</h3>
It is a chemical molecule of the second generation known as an amphiphile, with both hydrophilic and lipophilic qualities.
- In contrast to any other organic solvent, water is used for transition metal catalysed cross-coupling, making TPGS-750M a second generation surfactant with physical features that encourage this process.
- The hydrophilic portion of TPGS-750M, which is utilised in medicine, is made of Poly(ethylene glycol), and the hydrophobic portion is made of the vitamin E compound alpha-tocopherol.

Answer: 253.8
Explanation:
The molar mass of iodine is 126.904. Multiply that by two and you get approximately 253.8 grams in two moles.
Number of alpha decays is 4.
₉₀Th²³² → ₂He⁴ + ₈₈Ra²²⁸ ∴ α = ₂He⁴
Since, atomic number change by 2 in each alpha decay.
Total charge = 90 -82 = 8
Number of alpha decay = 8/2 = 4.
Alpha decay or α-decay is a type of radioactive decay wherein an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into a extraordinary atomic nucleus, with a mass wide variety this is decreased through 4 and an atomic wide variety this is decreased through two.
Alpha decay - A common mode of radioactive decay wherein a nucleus emits an alpha particle (a helium-four nucleus). Beta decay - A commonplace mode of radioactive decay in which a nucleus emits beta particles. The daughter nucleus will have a better atomic number than the original nucleus.
