3. Oven-roasting the tri-tip roast Place roast in the oven and roast, uncovered, for 30 to 35 minutes or until the thermometer registers 135 degrees F. Remove from the oven and cover with foil. Let the meat stand for 15 minutes, which will bring the temperature up to 145 degrees F (medium rare) after standing.ou can also just sprinkle the meat with salt and ground black pepper before baking, then serve with a sauce or a topper of sauteed mushrooms and onions. 2. Prepping the tri-tip roast Preheat the oven to 425 degrees F. Place the roast on a rack in a shallow roasting pan.
The term electron-pair geometry is the name of the geometry of the electron-pair/groups/domains on the central atom, whether they are bonding or non-bonding.
Best Answer: The molecular geometry simply refers to the shape of the molecule without taking into account the lone pairs of electrons, which is what your professor was asking. Tetrahedral is the geometry when the lone pairs are considered, called the electron-pair geometry.Source(s):etrahedral is the geometry when the lone pairs are considered, called the electron-pair geometry.
