The volume of hydrogen gas produced by reaction of 0.25 -g piece of sodium and water is to be calculated. Concept introduction: The stoichiometry of a chemical species involved in a chemical reaction represents the number of chemical species involved in the chemical reaction. The stoichiometry of a chemical species helps in calculating the expected mass of reactant and product. The stoichiometry of a chemical species is also represented in a number of moles. The number of moles of a substance is given by the expression as shown below. n = m M

10. Complete the substitution reaction of 2 pentanol with these reagents. Reagents & Reaction Conditions use practice sheet. Please write only major products, minor product like water, other gases are not required. Hint: In substitution of alcohol, we generally substitute OH group with Halogens like cl, Br, F using some reagent containing halogens. Ensure to add halogens to the same carbon number where you are removing OH from Examples Alcohols can be converted to Alkyl Halides with HX acids HBr H₂O HCI + H₂O HI + H₂O CH,CH₂OH + SOCI₂ CH,CH₂OH + PCI₁₂ A BBYJU'S CH CHCI + SO₂+ HCI CH₂CH CIP(OH), + HCI CH,CH₂OH + PCI CHCHCI + POCI + HCI CH,CH₂OH + PBr, CH,CH,Br + P(OH), + HBr 1.
