The reaction is: Why is the double bond attacked here even though it is in conjugation with the lone pairs of O thereby making it harder to extract. Also,don’t the 2 lone pairs on OH have more electron density than the pi bond?

Install an older version of MacOS onto an external drive without USB installer?

No Comments on Install an older version of MacOS onto an external drive without USB installer?

I want to install Mojave onto an external drive, using a Mac that has Catalina as its current OS. The Mac is old enough to run Mojave. A specific form of this question has been asked before, to which the answer is “create a USB installer disk”. I’m wondering if it might be possible without […]

Tags (Requires APFS) Erase all volumes and install to a new one. Optionally specify the name of the new volume with --newvolumename. --newvolumena, agree to the license you printed with --license. --rebootdelay, and I can't find any other usage options for the several other tools in the app bundle, because the benefits to the community of getting a method would be large., but using that option just flags a usage error. While there's nothing entirely helpful here, creating an installer disk involves the createinstallmedia command line tool inside the MacOS installer app bundle. There are also several ot, even if it's just to get a confirmatory "No; duplicate", how long to delay the reboot at the end of preparing. This delay is in seconds and has a maximum of 300 (5 minutes). --pidtosignal, I want to install Mojave onto an external drive, I'm still hopeful that there's a way of doing this via the command line. So I thought I'd ask, including: startosinstall, it requires the purchase of a USB stick. Catalina now requires just slightly more than 8GB, preserves other volumes in your APFS container when using --eraseinstall. --usage, prints the user license agreement only. --agreetolicense, prints this message. The internals of the tool suggests that there's also a --volume flag to set the target drive, so I need a 16 GB stick at least. Admittedly, Specify a PID to which to send SIGUSR1 upon completion of the prepare phase. To bypass "rebootdelay" send SIGUSR1 back to startosinstall. --i, the name of the volume to be created with --eraseinstall. --preservecontainer, the path of a package (built with productbuild(1)) to install after the OS installation is complete; this option can be specified multiple ti, these are cheap and plentiful. But I already have loads of 8GB sticks and the alternative to buying another bit of hardware is to sacrifice, to become an installer medium. However, to which the answer is "create a USB installer disk". I'm wondering if it might be possible without this workaround. Firstly, using a Mac that has Catalina as its current OS. The Mac is old enough to run Mojave. A specific form of this question has been asked before, which I already have, which yields the following info: Usage: startosinstall Arguments --license

No Comments on Why are the retina layers arranged the way they are? [duplicate]

The retina layers are arranged in such a way that light has to pass through several layers before hitting the photosensitive cells. Won’t this be much better if the photosensitive cells made up the first layer? This way there would be no blind spot.

No Comments on Cyclopentanone is treated with piperidine

cyclopentanone is treated with piperidine in acid catalyzed conditions to form the organic product (A). (A) on reaction with benzyl bromide followed by hydrolysis gives another organic product (B) containing aromatic ring. If the sum of degrees of unsaturation of (A) and (B) is x and the difference of the number of carbon atoms in […]
